LTST-C281KRKT-5A 是 LITEON(台湾光宝)推出的一款单色表贴 LED,采用超小型 0402 封装,发出橙红色光。该器件为无色透明透镜设计,视角宽达 130°,适合需要微型指示、状态显示或点阵排列的高密度电路板应用。凭借小体积与良好的光电特性,适用于消费电子、可穿戴设备、仪器仪表及各类指示灯方案。
说明:上述光强、压降等参数受测试条件(如测试电流、环境温度、测试器件分档等级)影响,实际选型时请参考厂商正式数据手册和分选(bin)信息。
LTST-C281KRKT-5A 采用 0402 表贴封装,体积极小,有利于节省 PCB 空间并支持细间距阵列布置。透明透镜有利于光通量输出的一致性和色彩还原。该封装适用于常规 SMT 回流工艺,但对贴片、回流温度曲线和产线处理精度有较高要求。建议在设计 PCB 时预留合理焊盘并考虑热膨胀与焊锡扩散影响。
LTST-C281KRKT-5A 属于 LITEON 常见的小功率 SMD LED 产品线,建议在设计前获取并参考官方数据手册,确认具体电气曲线、尺寸图、回流曲线与分档说明。批量采购时可与供应商沟通光强与色度分档要求,以保证成品一致性。
总结:LTST-C281KRKT-5A 以其超小 0402 封装、宽视角与稳定的橙红色发光特性,适合空间受限且需要可靠指示的应用场景。合理的电流控制与热管理、遵循制造与储运建议,可确保长期稳定运行与一致的显示效果。

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.
