XL-3528SURUBC-FJ是成兴光(Xinglight) 推出的红蓝双色贴片发光二极管,采用SMD-4P封装,尺寸为3.5×2.8mm,载带方式为正贴,适配自动化贴片生产工艺。该器件通过反极性设计实现红蓝双色切换,无需额外切换电路,简化了终端产品的布线与成本控制,是工业控制、消费电子等领域状态指示的优选器件。
正接时红色发光,反接时蓝色发光,通过正负极切换即可实现色彩转换,无需额外驱动电路,降低了设计复杂度。
采用无色透明透镜,无额外滤光损耗,保证光输出效率,长期使用无黄变或光衰加速问题(需避免强光直射)。
设计电路时需匹配不同颜色的压降需求,例如红色接5V电源时,串联150Ω左右电阻限流;蓝色则需调整电阻至80Ω左右(公式:(R=(V_{电源}-Vf)/If))。
工作温度范围为**-40℃+85℃**,覆盖工业级(通常-4085℃)及部分车载环境,适合户外设备、工业控制板等宽温场景。透镜采用耐温材料,可承受贴片回流焊的峰值温度(260℃以内),手工焊接需控制烙铁温度<300℃,避免损坏透镜或芯片。
该器件凭借双色反极性、宽温可靠性及高亮度特性,在多领域实现了低成本、高性能的状态指示需求,是贴片LED市场的实用型选择。

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.
