XL-2520UGC/TR10 是成兴光(Xinglight)推出的一款翠绿色贴片发光二极管,封装为 SMD 小体积 2.3 × 2.1 mm(2520 封装),外观为小蝴蝶形(butterfly),单独二极管结构,透明透镜,载带方式为反贴(reverse tape)。该器件适用于需要高显色性和小光斑的指示、背光及精细照明场合。
在 20 mA 工作点下,最大 Vf(3.2 V)对应耗散约 64 mW,低于器件额定 70 mW,使用时仍建议适当余量与降额设计。
细小封装利于高密度 PCB 布局,但在手工焊接与检修时需注意定位和夹持。
采用恒流驱动是最佳实践;若使用串联限流电阻,计算公式为 R = (Vs − Vf) / If。以 Vf 取典型 3.0 V、If = 20 mA 为例:
电阻功耗 P = I^2 × R,应选择合适功率等级。若并联多只,注意共模电流分配及热平衡,建议每只 LED 单独限流或使用恒流驱动器以保证亮度一致性。
总结:XL-2520UGC/TR10 以其小型封装、窄发散角和纯正翠绿色光色,适合对光学指向性与色彩要求较高的应用场合。在实际设计中应采用恒流或合适的限流电路、重视热管理与 ESD 防护,以保证长期稳定性与亮度一致性。若需完整电气/机械图和回流曲线,请索取成兴光官方数据手册。

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.
