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.
electrical-limits
Coverage ID: cov-c21189-electrical-limits · Status: COVERED
Reason: Jumper resistance (<50 mOhm), rated current (1A), overload current (2A), and operating temperature are all primary-source confirmed from the UNI-ROYAL 0603 jumper ratings row.
Facts in this domain:
pulse-energy-at-installed-waveform
Coverage ID: cov-c21189-pulse-energy · Status: OPEN
Reason: Rated/overload current alone does not establish a pulse-energy rating for the installed CCDB bridging waveform.
Facts in this domain:
Blocked by: these facts must be resolved before the domain can close. Each is listed in full under Facts.
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.
RECOMMENDED_OPERATION
The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.
Fact: fact-c21189-rated-current
Value: 1 · Unit: A
Conditions: 0603 jumper rated current
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC

A parameter the manufacturer guarantees over the stated conditions, usually with minimum, typical and maximum values.
Fact: fact-c21189-jumper-resistance
Value: less than 50 milliohm · Unit: NONE
Conditions: 0603 jumper; do not model as an ideal zero
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC

TRANSIENT
Behaviour during a short event — startup, a switching edge, a fault or a surge.
Fact: fact-c21189-overload-current
Value: 2 · Unit: A
Conditions: 0603 jumper maximum overload current
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-c21189-uniroyal — Section evidence: page 5, Ratings table, 0603 jumper row
Fact: fact-c21189-pulse-caveat
Value: Jumper pulse energy at the installed CCDB waveform is unknown · Unit: NONE
Conditions: rated/overload current alone does not specify pulse energy
Verdict: NEEDS BENCH · Provenance: PRIMARY-SPEC
Evidence: src-c21189-uniroyal — Section evidence: page 5, Ratings table, 0603 jumper 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-c21189-manufacturer
Value: UNI-ROYAL · Unit: NONE
Conditions: exact orderable 0603WAF0000T5E
Verdict: PASS - primary-source confirmed · Provenance: PRIMARY-SPEC
Evidence: src-c21189-uniroyal — Section evidence: page 2, Scope paragraph 1.1 and Part No. System
Fact: fact-c21189-topology
Value: R19 (0 Ohm, fitted) bridges CC1DB to CC1, restoring the ST reference dead-battery termination (DS12499 3.5); R20 (0 Ohm, fitted) mirrors this for CC2DB/CC2 -- see board-a-usb-pd-core.md CC1DB/CC2DB net rows · Unit: NONE
Conditions: current board-a-usb-pd-core.md net tables
Verdict: NOT APPLICABLE · Provenance: REFERENCE-DESIGN

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.

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.

Provenance
| Recorded term | What it means |
|---|---|
