1. Identify the documented electrolyte construction
Start with the manufacturer, complete product code and available series identification. An aluminium-can appearance or a warehouse entry saying electrolytic does not settle the electrolyte construction of the offered variant. Retain the source of each reading, including original packaging and purchase records where available. If the code is incomplete, preserve that gap instead of choosing a familiar construction from the enclosure.
Use separate words for the categories supported by the applicable documentation. Panasonic's construction comparison distinguishes an electrolyte-liquid category, a conductive-polymer category and a hybrid category containing both conductive polymer and electrolyte liquid. This is a useful classification example. It does not establish which construction is present in an unidentified seller's container or assign specifications to another manufacturer's series.
Record a description such as liquid-electrolyte only when the actual series evidence supports it. Keep the exact source terminology where translation or a shortened stock label could obscure the distinction. The related storage-and-endurance guide concerns non-solid aluminium electrolytics; identifying construction first tells the reviewer whether that guide's stated scope is relevant to the line under consideration.
2. Preserve hybrid as its own category
Give hybrid its own inventory category rather than merging it into a broad polymer group. The Panasonic electrolyte row retains a liquid constituent together with conductive polymer. Dropping either part changes the description being communicated. A recipient comparing released stock should be able to see the supported construction without having to reconstruct it from a manufacturer's name or a sales category.
When an internal list says polymer but the series document says hybrid, keep the original stock label and the supported construction separately. Ask the owner to reconcile the record rather than silently rewriting the source label. That distinction is particularly useful when several capacitor series were purchased for one programme and later consolidated into a single warehouse category.
The construction row supports this category decision, not a performance ranking. Do not import neighbouring marketing claims, numerical comparisons or replacement examples into the lot description. A hybrid designation does not by itself establish the offered part's leakage, ripple-current behaviour or suitability for another series' application. Those questions require the exact product information and the intended use, separately from inventory classification.
3. Separate category from storage and endurance
Keep construction identity, storage evidence and any existing electrical assessment in different fields. The first says what the documented product is. Storage records describe what is known about its history. A dated report says what was assessed for identified material. None of these fields should overwrite the others simply because the seller wants one short description of stock condition.
If storage records are unavailable, say so without assigning a universal expiry threshold to the construction category. Date codes can support identification and traceability, but the passage of calendar time alone does not produce a remaining-life result in this enquiry. Similarly, an endurance statement from a product document should retain its own conditions instead of becoming an estimate of usable hours for the offered lot.
Describe visible can, sleeve, terminal or seal issues only where observed and link the observation to the relevant group. Preserve any existing treatment or measurement record with its actual scope. This article supplies no treatment procedure or condition assessment. A confirmed liquid, solid-polymer or hybrid identity should not be used to prescribe handling copied from a different capacitor construction.
4. Submit construction-supported groups
Prepare groups by exact code and supported construction, with packaging and history distinctions retained for their actual quantities. Keep unknown-series material separate from lines whose construction is documented. If only part of a container can be linked to original records, state that coverage. Avoid assigning the construction of one readable sample to every visually similar capacitor in the container. Keep a generic mixed-capacitor container as a mixed entry until its exact series records support narrower construction groups and their respective quantities.
Use the stock-list guide for the released quantity, location, ownership and supporting records. Add a source reference for each construction description and identify any disagreement with the existing inventory wording. The practical outcome is a reviewable list showing which material is liquid-electrolyte, conductive-polymer-solid, hybrid or still unresolved, rather than a bulk total advertised under one ambiguous category.
For an ICULTRA enquiry, submit those identified groups and explain missing series or history information. The next decision is whether the recipient can assess the actual material and what further records it needs. Construction classification does not establish purchase eligibility, a price, electrical condition or remaining life. Any acceptance, inspection scope and transfer terms must concern the particular lines and be confirmed separately.
