750 mA PPTC fuse — BHFUSE — C976305 — board-l F1 — rec-bsmd1206-075-30v

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.

hold-trip-voltage-current-time-resistance

• Coverage ID: cov-bhfuse-electrical

• Status: COVERED

Reason: fact-bhfuse-hold-25c through fact-bhfuse-resistance-reset-max

Facts in this domain:

• fact-bhfuse-hold-25c

• fact-bhfuse-trip-25c

• fact-bhfuse-voltage-max

• fact-bhfuse-fault-current-max

• fact-bhfuse-trip-power-typ

ambient-derating-cycling-reset-processing-package

• Coverage ID: cov-bhfuse-thermal

• Status: COVERED

Reason: fact-bhfuse-hold-85c through fact-bhfuse-package

Facts in this domain:

• fact-bhfuse-hold-85c

• fact-bhfuse-temperature

• fact-bhfuse-surface-temperature

• fact-bhfuse-reset-definition

• fact-bhfuse-cycling

• fact-bhfuse-process-warning

• fact-bhfuse-package

fault-current-ambient-and-cycling

• Coverage ID: cov-bhfuse-fault

• Status: OPEN

Reason: The generator does not bound upstream fault current/energy, ambient/local heating, trip count, cooling interval, or downstream normal-load envelope.

Facts in this domain: none are recorded against it.

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.

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.

TYPICAL_CURVE

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

TRANSIENT

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

THERMAL_SOA

Thermal and safe-operating-area behaviour: how much the part may dissipate, and under what mounting and ambient conditions.

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.

• Footprint: F1206

• 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-bhfuse-input-protection

• Records involved: rec-bsmd1206-075-30v (this record)

• Conditions: actual source fault current/voltage, ambient/local heat, normal load, trip history, and cooling interval

• Verdict: NEEDS BENCH

Facts this rests on:

• fact-bhfuse-hold-25c

• fact-bhfuse-trip-25c

• fact-bhfuse-time-trip

• fact-bhfuse-hold-85c

• fact-bhfuse-cycling

• fact-bhfuse-project-nets

• fact-bhfuse-voltage-margin

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-rail-envelope — rail-envelope — rule verdict: UNSOURCED — Whether every part on the input rail stays inside its own recorded limits across a legal power contract, a mis-contract, and a transient clamp event.

• rule-c5446803-power-cut — board-mounted lamp power switching — rule verdict: NEEDS BENCH
