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-grm32er71h106ka12l-identity · Status: COVERED
Reason: Exact MPN/LCSC binding retained.
Facts in this domain:
loaded operation and physical validation
Coverage ID: cov-grm32er71h106ka12l-application · Status: OPEN
Reason: The final assembled circuit needs loaded thermal, transient and physical validation; stated typical or mirror-only evidence is not a guaranteed application result.
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.
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.

Value: 27.54 · Unit: uF
Conditions: Five parallel units: 50 uF x0.8 DC-bias allowance x0.9 tolerance x0.85 temperature x0.9 aging. The bias/aging factors are design assumptions requiring validation, not a guaranteed bound. Two input units under same model give 11.016 uF.

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:

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.

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. |
NEEDS BENCH | Cannot be settled from documents. It needs measurement on real hardware before it can be relied on. |
NOT APPLICABLE | The parameter does not apply to this part as it is used here. |
UNSOURCED | No accepted source backs this value yet. Treat it as a claim, not a fact. |
Provenance
| Recorded term | What it means |
|---|---|
DISTRIBUTOR-IDENTITY | Taken from a distributor listing. Identity information only. |
PROJECT-CHOICE | A decision made by this project. No vendor asserts it. |
UNVERIFIED | Recorded, but not yet backed by an accepted source. |
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. |
TYPICAL_CURVE | A representative figure read from a characteristic curve. Typical values are not guaranteed and vary part to part. |
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_MIRROR | A copy of a manufacturer document hosted elsewhere. Usable, but weaker than the manufacturer's own copy. |
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`. |
