TJ-S3527UG2W4TLCDWTW-A5 是 TOGIALED(统佳)出品的高可靠性白光 SMD 发光二极管,采用行业常用的 SMD3528 封装,单颗独立二极管设计,适用于要求一致性、可批量贴装的常规背光和指示照明场景。产品提供冷白与暖白两档色温选择,满足不同光色需求。
该器件在 20mA 驱动下提供稳定的白光输出,冷白与暖白两种 CCT 可覆盖从偏暖到偏冷的视觉需求。正向压降范围 2.8–3.4V,实际电压随色温和生产批次略有差异,设计驱动电路时请按照典型 Vf 值并预留余量。发光角度 120°,适合面状照明与均匀背光布光。
SMD3528 小型封装,便于自动化贴装与回流焊工艺。推荐按照厂家提供的 PCB 焊盘尺寸与回流温度曲线进行设计与焊接,避免过高的回流峰值温度和过长的停留时间。器件为独立二极管,单元间不共阴或共阳时可单独驱动或并联使用,注意确保电流均衡。
工作温度范围宽(-40℃~+80℃),适应多种环境。为延长寿命和保持光通稳定,建议在高温环境下进行电流降额管理并优化 PCB 散热(增加铜箔面积或热通道)。遵循 ESD 防护(HBM)和湿敏等级规范,避免在搬运与装配过程中静电或潮气损伤。
适用于家电面板指示、仪器仪表背光、消费电子指示灯、汽车内饰照明(非车外照明)等。驱动方式推荐恒流驱动器或限流电阻与稳定电源结合使用;并联多颗时应采用独立限流或配对电阻以保证电流均匀分配。
标准带卷包装,适配贴片机自动上料。订购时请注明色温(冷白/暖白)、最小起订量及交付批次要求,如需样品或详细封装图、焊盘建议请联系 TOGIALED 技术支持获取完整数据手册与可靠性报告。

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.
