NCD0603B4 是国星光电(NationStar)推出的一款0603 封装蓝光贴片发光二极管。器件在20 mA 驱动电流下提供稳定的蓝色发光,峰值波长约465 nm,常见发光波段为466–478 nm。小体积、高亮度与宽视角相结合,适合对空间和封装密度有较高要求的电子终端指示与背光应用。
0603 封装尺寸小,便于高密度贴装与微型化产品设计。该封装对焊盘设计与回流焊工艺要求较高,推荐参考国星光电的PCB焊盘与回流温度曲线以保证焊点质量与器件可靠性。0603 LED 适合自动贴装,适配常见贴片机与回流生产流程。
在20 mA 驱动下器件耗散功率最高可达约72 mW,应注意整体热管理与散热路径设计,避免长期在高温下满载工作导致光衰。建议在高温环境下进行电流降额以延长寿命。器件对静电敏感,生产与测试过程需做好ESD 防护。采用恒流驱动或合适的限流电阻可保证稳定发光并防止过流损坏。
本产品由国星光电生产,适用于对微型化与可靠性要求较高的蓝光指示与背光场合。选型与最终电路设计建议参考厂方详细规格书与可靠性数据。

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.
