EVERLIGHT(台湾亿光)型号 19-21/BHC-AP1Q2/4T 为一颗高亮蓝色贴片发光二极管(SMD),采用微小 0603 封装。该器件发光波长集中于 464.5nm~476.5nm,峰值 468nm,透镜为无色透明,发光角度约 100°,适合空间受限场合的指示与背光应用。器件额定正向电流为 20mA,单颗功率上限 75mW,工作温度范围 -40℃ 到 +85℃。
为确保稳定与安全,建议使用恒流驱动或在电源与 LED 串联限流电阻。常见电源下的限流电阻示例(目标 If = 20mA):
注意:电源波动、器件 Vf 公差及温升都影响实际电流,恒流驱动能提供最稳定与可靠的亮度控制。
该 0603 蓝色 LED 以体积小、视角宽、峰值光谱稳定为特点。若需更高亮度或更低 Vf 可考虑其他封装(1210、0805 等)或不同型号;若需更严格光色一致性或更高温度耐受性,请参照亿光完整数据手册并与供应商确认批次光学分级(BIN)与可靠性报告。
备注:本文为产品概述与常规设计建议,具体电气极限、回流曲线、光学分级与可靠性数据请以亿光官方数据手册为准,并在量产前进行样品验证与可靠性测试。

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.
