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.

exact orderable identity

Coverage ID: cov-rt0603bre07158kl-identity · Status: COVERED

Reason: Exact MPN/LCSC binding retained.

Facts in this domain:

Blocked by: no blocking fact is recorded. What is missing has not been reduced to a specific recorded fact, so the reason above is the whole of what is known.

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.

GUARANTEED_ELECTRICAL

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

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.

Records involved: rec-rt0603bre07158kl (this record)
Conditions: U2 13.44 V nominal pre-regulator at 1.2 A synth rail budget; low-line, startup, temperature and capacitance assumptions require final integration review.
Verdict: NEEDS BENCH

Facts this rests on:

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.

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
`CONFIRMED - distributor identity only`	A distributor listing confirms which part this is, and nothing more. It carries no electrical, thermal or lifetime authority.
`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
`DISTRIBUTOR-IDENTITY`	Taken from a distributor listing. Identity information only.
`PRIMARY-SPEC`	Taken from the manufacturer's own specification document.
`PROJECT-CHOICE`	A decision made by this project. No vendor asserts it.

Fact class

Recorded term	What it means
`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.
`THERMAL_SOA`	Thermal and safe-operating-area behaviour: how much the part may dissipate, and under what mounting and ambient conditions.

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
`DISTRIBUTOR_IDENTITY`	A distributor listing. Establishes which part this is, nothing more.
`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
`VERIFIED`	The exact orderable part has been confirmed against a source.

Source state

Recorded term	What it means
`AVAILABLE`	At least one document backing this line was retrieved.

Unit

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