0603WAF1003T5E

100 kOhm resistor — UNI-ROYAL — C25803 — board-p R11; board-l R26, R22 — rec-c25803

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.

• Coverage ID: cov-c25803-rating

• Status: COVERED

Reason: fact-c25803-manufacturer; fact-c25803-resistance; fact-c25803-tolerance; fact-c25803-power; fact-c25803-tcr; fact-c25803-voltage

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.

RECOMMENDED_OPERATION

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

GUARANTEED_ELECTRICAL

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

TRANSIENT

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

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.

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.

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.

• Symbol: 0603WAF1003T5E

• Footprint: R0603

• Pins: 2

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-c25803-r11

• Records involved: rec-c25803 (this record)

• Conditions: Board P R11 is Q1-gate to VBUS_IN; active-device state determines actual stress; Board L R26 is the NTC divider top from V3P3 to NTC_SENSE

• Verdict: NEEDS BENCH

Facts this rests on:

• fact-c25803-resistance

• fact-c25803-rcwv-squared

• fact-c25803-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-usb-pd-nvm-load-switch — usb-pd-nvm-load-switch — rule verdict: UNSOURCED — How the power-delivery controller's stored configuration and its enable output drive the load switch, through every state from detached to fault.

• rule-ntc-adc-firmware — ntc-adc-firmware — rule verdict: UNSOURCED — How the thermistor, its divider, the analog-to-digital input and the firmware that reads them combine into a temperature the design can act on.

• rule-c470643-brightness-adc — potentiometer-brightness-adc — rule verdict: NEEDS BENCH
