Coverage

Coverage is stated one domain at a time and is never rolled up. A domain marked open is a question that has not been answered; it is not a finding that the part is unsuitable. A record with no open domains has not thereby been declared safe.

electrical-limits

Coverage ID: cov-c2983319-electrical-limits · Status: COVERED

Reason: Capacitance (470uF), tolerance (+/-20%), and rated voltage (25V) are confirmed from the manufacturer datasheet, cross-checked against the LCSC product-detail page.

voltage-rating-vs-rail

Coverage ID: cov-c2983319-rail-margin · Status: COVERED

Reason: 25V rating against the inventory-declared +13.5V rail gives an 11.5V margin.

Facts in this domain:

fact-c2983319-rail-margin

c11-rail-assignment

Coverage ID: cov-c2983319-net-discrepancy · Status: COVERED

Reason: Resolved against the generator spec, which is the source of truth for placement: board_b_spec.py NETS puts C11.2 on '/DC-DC Conversion/-13.5V OUT' and C3.1 on '/DC-DC Conversion/+13.5V OUT'. That matches the board-b doc's U4 net table, the locked baseline, and the sheet-geometry adjacency probe recorded in BB-12; inventory.json's function text was the lone outlier and is corrected. The 11.5 V margin is unaffected -- it was already computed against a 13.5 V magnitude, which both rails share.

Facts in this domain:

fact-c2983319-c11-net-discrepancy

switching-frequency-ripple-current

Coverage ID: cov-c2983319-ripple-esr · Status: OPEN

Reason: The manufacturer RATING is now fully sourced: 240 mA rms @120Hz/105C with a x1.30 multiplier at 10kHz and above, giving 312 mA rms at the project's 150kHz switching frequency, and max ESR ~0.51 Ohm derived from the specified tan-delta. The earlier partial-extraction figures (approx. 1.0A ripple, approx. 0.035 Ohm ESR) were wrong by ~4x and ~14x respectively, both in the non-conservative direction, and have been superseded. The domain stays OPEN because applying the rating shows a problem rather than clearing one. C24's line now carries ripple and ESR facts too (fact-c22387780-ripple-hf-derate, fact-c22387780-esr-120hz), so the C11 || C24 split the review could not bound is now computable: splitting the review's ~0.77 A by the two parts' max-ESR ratio originally gave C11 ~362 mA against its 312 mA rating (~1.16x over) and C24 ~408 mA against 403 mA (~1.01x). The C11 || C24 exceedance is resolved by resize: decision neg-rail-cap-bank adds C12 (a second C22387780) in parallel, putting C11 at ~248 mA = 79.6% of its 312 mA rating in the three-can split (fact-c2983319-c11-ripple-share-3can) -- that share is now on the Vsat-inclusive ~0.807 A ripple basis issue #171 established (fact-lm2596-vsat), and reaches 80.6% at the guaranteed max Vsat, still inside the 85% bar. C3 is far less exposed -- a buck output cap carries only inductor ripple, not the pulsating diode current C11 sees. Needs a bench measurement -- issue #155, BB-7.

fact-c2983319-ripple-esr-note

case-size

Coverage ID: cov-c2983319-case-size · Status: COVERED

Reason: The manufacturer datasheet states the case size three independent ways on page 1 -- the header line 'GVT, 25v, 470uF, 8x10.5', the Description line 'D8H10.5mm', and the Dimension & Marking table Case row 'Phi 8x10.5' with A 8.3 / B 8.3 / C 9.0 / D 8.0 / P 3.1 / L 10.5. Those map digit-for-digit onto zudo-pd:CAP-SMD_BD8.0-L8.3-W8.3-LS9.0-FD, which is now the assigned land. This closes issue #150: the part is Phi 8, not Phi 10, so no design decision was required -- the previous BD10.0 assignment was simply wrong.

Facts

Each fact keeps its value, its unit, the conditions it holds under, where it came from and how far it has been confirmed as separate fields, because they are separate claims. A value without its conditions is not the same fact, and a verdict is about the evidence for the value, not about the part.

TYPICAL_CURVE

A representative figure read from a characteristic curve. Typical values are not guaranteed and vary part to part.

Fact: fact-c2983319-ripple-esr-note

Value: The manufacturer's ripple rating and its frequency derating are both fully specified on page 1 and are now recorded as first-class facts (fact-c2983319-ripple-120hz, fact-c2983319-ripple-freq-multiplier, fact-c2983319-ripple-hf-derate): 240 mA rms @120Hz/105C, x1.30 at 10kHz and above, giving 312 mA rms at the project's 150kHz switching frequency. This SUPERSEDES the earlier partial-extraction figures of approx. 1.0A @120Hz/85C and approx. 0.035 Ohm ESR, both of which were wrong -- the ripple by ~4x and the ESR by ~14x (see fact-c2983319-esr-120hz: tan-delta implies ~0.51 Ohm), each in the non-conservative direction, and the endurance temperature was misstated as 85C where the datasheet specifies 2000 h at 105C. What remains unverified is the INSTALLED ripple current at C3 (U2 +13.5V buck output filter) and C11 (U4 inverting buck-boost output filter, the higher-stress position) against that 312 mA rating; that is a bench measurement, tracked as BB-7. · Unit: NONE

Conditions: installed switching-frequency ripple current vs the manufacturer-derated rating

Verdict: NEEDS BENCH · Provenance: PRIMARY-SPEC

Evidence: src-c2983319-datasheet — Page 1, Ratings table row Ripple Current, and table Ripple Current and Frequency Multipliers

PROJECT_STATE

A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification.

Fact: fact-c2983319-manufacturer

Value: HRK · Unit: NONE

Conditions: exact orderable GVT1E477M0810CNVC

Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC

Evidence: src-c2983319-datasheet — Title block / manufacturer identification, LCSC product-detail page cross-check

Fact: fact-c2983319-case-size

Value: Phi 8.0 x 10.5 mm V-chip can. Dimension table: A 8.3, B 8.3, C 9.0, D 8.0, P 3.1, L 10.5, W 0.8-1.1, H 0.5 max (mm). The matching KiCad land is zudo-pd:CAP-SMD_BD8.0-L8.3-W8.3-LS9.0-FD, whose BD/L/W/LS fields correspond digit-for-digit to D/A/B/C. NOT the Phi 10 CAP-SMD_BD10.0-L10.3-W10.3-LS11.0-FD land this part was assigned in board_b_spec.py through v0.4.0 -- see issue #150. · Unit: NONE

Conditions: case size and matching land pattern

Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC

Evidence: src-c2983319-datasheet — Page 1, header line 'GVT, 25v, 470uF, 8x10.5', Description line 'D8H10.5mm', and the Dimension & Marking table (Case row 'Phi 8x10.5')

Fact: fact-c2983319-rail-margin

Value: 11.5 · Unit: V

Conditions: C3 sits on the +13.5V rail and C11 on the -13.5V rail (resolved -- see fact-c2983319-c11-net-discrepancy). Both rails have a 13.5V magnitude, so the margin is the same at either position: 25V rating - 13.5V = 11.5V.

Verdict: PASS - primary-source confirmed · Provenance: CALCULATED

Evidence: src-c2983319-boardbdoc — scripts/schgen/board_b_spec.py NETS ('/DC-DC Conversion/+13.5V OUT' C3.1, '/DC-DC Conversion/-13.5V OUT' C11.2); board-b-synth-power.md DC-DC net tables (U2/U4 sections)

Fact: fact-c2983319-c11-net-discrepancy

Value: RESOLVED: C11 sits on the -13.5V rail, C3 on the +13.5V rail. The generator spec is the source of truth for placement and states it unambiguously -- board_b_spec.py NETS puts C11.2 on '/DC-DC Conversion/-13.5V OUT' (beside U4.3/U4.5/U4.6, D3.2, C9.2, C24.2, U8.2) with C11.1 on GND, and C3.1 on '/DC-DC Conversion/+13.5V OUT' with C3.2 on GND. That agrees with the three independent reads BB-12 already had (board-b-synth-power.md's U4 net table, the locked baseline's -13.5V OUT row, and the sheet-geometry adjacency probe). inventory.json's line-level function text was the sole outlier and has been corrected to describe both refdes. This fact records the resolution; it no longer blocks. Note this does NOT settle pin-1/pin-2 polarity, which remains UNCONFIRMED in the pin map. · Unit: NONE

Conditions: cross-source discrepancy, resolved against the generator spec

Verdict: NOT APPLICABLE · Provenance: REFERENCE-DESIGN

Evidence: src-c2983319-boardbdoc — scripts/schgen/board_b_spec.py NETS entries '/DC-DC Conversion/-13.5V OUT' (C11.2) and '/DC-DC Conversion/+13.5V OUT' (C3.1); board-b-synth-power.md U4 net table; baselines/board-b.json -13.5V OUT row

Fact: fact-c2983319-c11-ripple-share-3can

Value: 248.27895475606644 · Unit: mA

Conditions: C11's share of the 0.807 A rms output ripple on '/DC-DC Conversion/-13.5V OUT' after decision neg-rail-cap-bank adds C12, i.e. the three-can bank C11 || C24 || C12 at the 0.8 A rated load. Ripple divides as conductance 1/ESR because ESR dominates each branch at the LM2596's 150 kHz. Against fact-c2983319-ripple-hf-derate (312 mA) this is 79.6%, inside the 85% sizing bar. VSAT-INCLUSIVE BASIS (issue #171 resolved): the expression's bare numbers are D = (13.53 + 0.55) / (15 - 1.16 + 13.53 + 0.55) = 0.5043 and Irms = 0.8 * sqrt(D/(1-D)) = 0.8069 A, where 13.53 V is the U4 setpoint magnitude (fact-lm2596-u4-vout-setpoint-magnitude), 0.55 V the SS34 catch-diode drop (fact-ss34-vf), 15 V the nominal input (fact-lm2596-vin-project), 1.16 V the LM2596 typical switch saturation voltage (fact-lm2596-vsat) and 0.8 A the rated -12V rail load; those four inputs are inlined as constants because the validator scopes depends_on to this bundle. SENSITIVITY at the guaranteed maximum Vsat (fact-lm2596-vsat-max, 1.5 V over temperature; 1.4 V at 25C): Irms rises to 0.817 A and this share to 251.4 mA = 80.6% (250.5 mA = 80.3% at the 25C limit) -- still inside the bar. C11 is the binding member of the bank: holding typical Vsat, the +15 V input would have to sag to 13.29 V before C11 reaches 85%, against 10.36 V for C24/C12; no retained fact bounds the +15 V rail low, so that axis stays with the existing NEEDS BENCH rather than carrying an assumed low-line number. The split uses 120Hz max-ESR because neither datasheet publishes ESR at 150kHz; the absolute Ohm values are pessimistic while the ratio between two same-technology, similar-size cans is the trustworthy part.

Verdict: NEEDS BENCH · Provenance: CALCULATED

Evidence: src-c2983319-boardbdoc — calculated from the ESR rows of both records (fact-c2983319-esr-120hz, fact-c22387780-esr-120hz) against the Vsat-inclusive 0.807 A output-cap ripple of spec-architecture-review.md section BB-7; duty-cycle inputs per fact-lm2596-vsat, fact-ss34-vf, fact-lm2596-vin-project and fact-lm2596-u4-vout-setpoint-magnitude; bank membership per board_b_spec.py NETS row '/DC-DC Conversion/-13.5V OUT'

Interactions

Behaviour that is not a property of this part alone. Each interaction names the records it spans, the conditions it holds under, and how far it has been confirmed. An interaction that spans several parts appears on every one of their pages, under the same identifier, because it is equally a fact about each.

No interaction is published for this record.

Cross-component rules

Rules that span several parts at once and are published in full on the integration page. Each rule's verdict below is that rule's own — it is a statement about the cross-component question, not about this part — and the exact wording of what the rule refuses to conclude is published with the rule itself.

No cross-component rule names this record.
