XL-B524SURSYGW 是成兴光(Xinglight)推出的一款直插式 5mm 圆头发光二极管,采用共阳极(共阳)二极管配置,提供红色与黄绿色两种发光单元,并配以雾状(漫射)透镜,光束均匀、视觉柔和。典型应用包括面板指示、仪表灯、状态指示与低功耗显示场合,适合需要较小发光角和明确色彩指示的产品。
XL-B524SURSYGW 为共阳极设计:所有发光单元共用一个阳极引脚(接正电源),各颜色的阴极为独立引脚。常见连接方式有:
注意:即便共用阳极,也应为每个颜色选用独立限流电阻以确保亮度可控且不超载。
推荐工作电流为 20 mA(连续),以下为常见电源下的限流电阻与功耗示例(取近似 Vf):
在 5V 电源下:
在 12V 电源下:
LED 自身功率:P_LED ≈ Vf × If(红色约 2.3×0.02 = 0.046 W,黄绿约 2.4×0.02 = 0.048 W),靠近 50 mW 标称值,上限不可超载。
总结:XL-B524SURSYGW 以其共阳方便连接、雾状透镜提供柔和视觉、较高发光强度与集中的发光角,适合对颜色区分与可视性有较高要求的指示场合。设计时注意限流、散热与 ESD 防护,即可获得稳定可靠的使用效果。

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.
