BT-102GEK-31-572D 是国星光电推出的一款高亮度 3mm 圆形插件 LED,发光色为黄绿色(峰值波长 572nm)。采用无色透明透镜和窄光束设计(发光角度 30°),适合需要集中照明和显著指示效果的场合。典型正向电压为 2.0V,额定正向电流 25mA,单只额定功率 75mW,工作温度范围为 -25℃ 至 +85℃。
注:上述为关键参数摘要,工程应用时请以厂家完整数据表为准。
典型恒流驱动为最佳选择,若使用串联限流电阻,可按欧姆定律计算: R = (Vs - Vf) / If
示例(以额定 If = 25mA 为例):
更可靠的方法是使用恒流源或 LED 驱动 IC,可实现稳定亮度和更好的长期可靠性。对于频繁开关或需要亮度可调的场合,推荐 PWM 调光与恒流驱动结合使用。
总结:BT-102GEK-31-572D 以其集中的 30° 光束、黄绿色 572nm 波段和标准 3mm 插件封装,适合对可视性和聚焦性能有较高要求的指示类应用。工程选型时,请结合工作环境、驱动方式和散热设计进行电气与热设计验证。若需完整技术规格或可靠性数据,请参照国星光电官方数据手册或联系供应商获取原始资料。

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.
