22 nF ceramic capacitor, DC-DC feedforward compensation — Samsung Electro-Mechanics — C1729 — board-b C32 (fitted), C33 (fitted) — rec-c1729

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.

Placements

Every position this exact line occupies in the as-built design. One line may be placed many times and across more than one board.

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-c1729-electrical-limits · Status: COVERED

Reason: Capacitance (0.022 uF), tolerance (+/-10%), rated voltage (50 Vdc), and dielectric (X7R, -55 to +125 C) are all primary-source confirmed.

Facts in this domain:

• fact-c1729-manufacturer

• fact-c1729-capacitance

• fact-c1729-tolerance

• fact-c1729-voltage

• fact-c1729-dielectric

effective-capacitance-under-installed-bias

Coverage ID: cov-c1729-bias-curve · Status: OPEN

Reason: Reference-sheet/specsheet DC-bias, temperature, and aging curves are design-reference only; the installed DC bias/ripple/temperature/layout point is not independently measured.

Facts in this domain:

• fact-c1729-curve-caveat

Blocked by: these facts must be resolved before the domain can close. Each is listed in full under Facts.

• fact-c1729-curve-caveat

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.

GUARANTEED_ELECTRICAL

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

TYPICAL_CURVE

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

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.

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.

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.

Sources

Every document cited above, with its identification, when it was retrieved, and what kind of authority it carries. Sources that could not be retrieved are listed too, with their unavailability stated, so a gap in the evidence is visible rather than absent.
