LTST-C281TBKT-5A 是 LITEON(台湾光宝)推出的一款超小型蓝色贴片LED,采用 0402 封装,透明透镜,发光角度宽达 130°,适合对体积与视角均有严格要求的消费电子与指示类产品。典型工作条件下的参数如下:正向电流 If = 5 mA,正向压降 Vf ≈ 2.9 V,峰值波长 468 nm,标称波长 475 nm,发光强度约 28.1 mcd。
注:在实际应用中,LED 的驱动功耗可由 Vf × If 计算(例如 2.9 V × 5 mA ≈ 14.5 mW);文档中给出的“功率 76 mW”应以原厂资料为准并与具体测试条件核对。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
