Generated from the component evidence records — edit the records, not this page.

Everything below is projected from this project's stored component evidence. Values keep the exact wording, conditions, units and verdicts they were recorded with — nothing here is re-typed, corrected, or combined into an overall judgement about the part.

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.

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.

ABSOLUTE_MAXIMUM

A never-exceed limit. Reaching it may damage the part; it is not an operating target and there is no margin implied by it.

Fact: fact-c22807-voltage

Value: 75 · Unit: V

Conditions: 0603 maximum continuous working voltage; overload max 150 V

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

Evidence: src-c22807-uniroyal: page 5, Ratings table, 0603 row

RECOMMENDED_OPERATION

The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.

Fact: fact-c22807-power

Value: 0.1 · Unit: W

Conditions: 0603 WA normal-size rating, ambient at or below 70 C

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

Fact: fact-c22807-rcwv-squared

Value: 15000 · Unit: V2

Conditions: P times R under source RCWV equation; use sqrt result and 75 V cap

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

Evidence: Section evidence, src-c22807-uniroyal: page 5, Derating Curve and RCWV equation

GUARANTEED_ELECTRICAL

A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.

Fact: fact-c22807-resistance

Value: 150000 · Unit: Ohm

Conditions: 1503 code: 150 times 10 to power 3

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

Fact: fact-c22807-tcr

Value: 100 · Unit: ppm/C

Conditions: 0603 resistance above 10 Ohm

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

Evidence: src-c22807-uniroyal: page 6, Temperature Coefficient table, 0603 row

TRANSIENT

Behaviour during a short event — startup, a switching edge, a fault or a surge.

Fact: fact-c22807-pulse-caveat

Value: No exact installed-waveform pulse-energy rating is retained · Unit: NONE

Conditions: only 5-second short-time-overload test is specified

Verdict: NEEDS BENCH · Provenance: PRIMARY-SPEC

Evidence: src-c22807-uniroyal: page 6, Short-time overload row

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-c22807-manufacturer

Value: UNI-ROYAL · Unit: NONE

Conditions: exact orderable 0603WAF1503T5E

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

Evidence: Section evidence, src-c22807-uniroyal: page 2, Scope paragraph 1.1 and Part No. System

Fact: fact-c22807-r12-topology

Value: R12 is 150 kOhm from VBEN to Q1_G · Unit: NONE

Conditions: current generated Board P netlist

Verdict: NOT APPLICABLE · Provenance: REFERENCE-DESIGN

Evidence: src-c22807-generator: NETS mapping, rows VBEN and Q1_G

Calculation dependencies

These values were derived from other recorded facts rather than read from a document. The expression and every input are published so the number can be recomputed instead of trusted. A derived value is never stronger than the weakest fact it depends on.

Fact: fact-c22807-rcwv-squared

Expression: fact_c22807_power * fact_c22807_resistance

Depends on:

fact-c22807-power
fact-c22807-resistance

Pin maps

The mapping between schematic pins and PCB pads, or physical terminals for an external part, as recorded. A record may carry more than one map when the same part is documented in more than one context.

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.

int-c22807-r12

Records involved: rec-c22807 (this record)
Conditions: Current R12 is 150 kOhm, not stale 56 kOhm prose; confirm active-device threshold and transient stress separately
Verdict: NEEDS BENCH

Facts this rests on:

fact-c22807-r12-topology
fact-c22807-resistance
fact-c22807-rcwv-squared
fact-c22807-pulse-caveat

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.

rule-q1-gate-drive-vs-contract — q1-gate-drive-vs-contract — rule verdict: NEEDS BENCH
rule-evidence-chain — source-to-bench-chain — rule verdict: UNSOURCED — How far each claim has travelled from a manufacturer document towards a measurement on real hardware, stage by stage.

Legend

What the recorded terms on this page mean, in ordinary words. The exact terms above are the ones that count; these descriptions explain them and never replace them.

Verdict

Recorded term	What it means
`NEEDS BENCH`	Cannot be settled from documents. It needs measurement on real hardware before it can be relied on.
`NOT APPLICABLE`	The parameter does not apply to this part as it is used here.
`PASS - primary-source confirmed`	Confirmed against the manufacturer's own document for this exact part.

Provenance

Recorded term	What it means
`CALCULATED`	Derived arithmetically from other facts listed here. The expression and every input are shown, so the number can be recomputed rather than trusted.
`PRIMARY-SPEC`	Taken from the manufacturer's own specification document.
`REFERENCE-DESIGN`	Taken from a vendor reference design or application note rather than the device specification.

Fact class

Recorded term	What it means
`ABSOLUTE_MAXIMUM`	A never-exceed limit. Reaching it may damage the part; it is not an operating target and there is no margin implied by it.
`GUARANTEED_ELECTRICAL`	A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.
`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.
`RECOMMENDED_OPERATION`	The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.
`TRANSIENT`	Behaviour during a short event — startup, a switching edge, a fault or a surge.

Coverage status

Recorded term	What it means
`COVERED`	Every question this domain asks is answered by the facts listed against it.
`OPEN`	Unresolved. Open means the question has not been answered, not that the part is unsafe — the reason states what is missing.

Source availability

Recorded term	What it means
`AVAILABLE`	The document was retrieved and is on record.

Source authority

Recorded term	What it means
`MANUFACTURER_PRIMARY`	The manufacturer's own document for this exact part.
`PROJECT_GENERATOR`	A document this project generated, such as a schematic or netlist export.

Identity state

Recorded term	What it means
`UNRESOLVED`	The exact orderable part is not yet confirmed. Substituting a same-name part from another vendor is not permitted on that basis.

Source state

Recorded term	What it means
`SOURCE UNAVAILABLE`	No document backing this line could be retrieved.

Unit

Recorded term	What it means
`NONE`	The value is not a physical quantity, so it carries no unit. Recorded as `NONE`.
