XL-257UGC-L 产品概述

一、型号与封装

XL-257UGC-L(品牌:Xinglight / 成兴光)是一款直插(插件)高亮绿光发光二极管,封装常见为5mm直径(L = 5 mm)长脚型,型号中常见描述“257m 白发翠绿长脚”用于区分外观与脚长样式。二极管为独立二极管配置,便于单点指示和逐个驱动控制。

二、光学性能

  • 发光颜色:翠绿色
  • 波长范围:520 nm ~ 530 nm
  • 峰值波长:525 nm
  • 发光强度(Iv):6 cd(典型)
  • 发光角度:35°(较窄的半角,方向性好)
    透镜为无色透明透镜设计,有利于获得更纯净的色彩和更明显的方向性光束。

三、电学与热学参数

  • 正向电流(If):20 mA(额定工作电流)
  • 正向压降(Vf):3.0 V ~ 3.4 V(在额定电流下)
  • 功率:70 mW(典型标称功耗)
  • 工作温度范围:-25℃ ~ +85℃
    在设计驱动电路时,应以If=20 mA和Vf范围作为基准,并考虑环境温度对Vf和亮度的影响进行必要的热与电气裕度设计。

四、主要特性与优势

  • 高亮度:6 cd 的标称亮度适合面板指示、仪表和可视化状态显示。
  • 纯色与窄角度:520–530 nm 的翠绿色与35°的发光角度,使其在需要集中指示光束的场合更清晰可辨。
  • 插件长脚:便于面包板试验、手工焊接和维修替换;适合通孔PCB安装。
  • 独立二极管:便于单通道控制与分散布局。

五、典型应用

  • 面板/指示灯、按钮背光与状态指示
  • 仪器仪表、电子测试设备、工业控制柜指示
  • 消费类电子设备的状态与功能提示
  • 需要方向性照明且颜色辨识度高的场合

六、使用与设计建议

  • 驱动方式:建议恒流驱动或在限流电阻的串联下使用,以保持稳定亮度并防止过流。
  • 串联限流电阻计算(示例,供参考):
    • 公式:R = (Vsup - Vf) / If
    • 若供电 5 V、Vf 取 3.0~3.4 V、If = 20 mA,则 R ≈ (5 - 3.4) / 0.02 = 80 Ω 到 (5 - 3.0) / 0.02 = 100 Ω,常用值可选 82 Ω 或 100 Ω。
    • 电阻耗散功率 P = Vdrop × I(在上述例子中最大约 2 V × 0.02 A = 0.04 W),1/4 W 电阻足够,但建议选用更高功率裕量以提高可靠性。
  • 热管理:在高环境温度或密集布置下应考虑适当降额,避免长期在极限温度和电流条件下工作。
  • 焊接与机械:插件式长脚在手工焊接时便捷;焊接时避免过长高温暴露以免影响封装和光学性能。
  • 储存与防护:避免潮湿、高温及强酸碱气氛,保持干燥包装直至使用。

七、采购与质量注意

选购时建议向供应商确认批次(binning)和出厂测试数据,尤其是电流-亮度一致性与波长分布,以满足对颜色或亮度一致性要求较高的用途。向品牌(Xinglight / 成兴光)或其授权经销商索取技术资料和样品进行实测验证,可降低项目风险。

总结:XL-257UGC-L 为一款面向指示与显示用途的高亮翠绿色 5mm 插件 LED,具有较窄发光角与稳定的光电参数,适合需要方向性强且颜色识别度高的指示应用。设计时按额定 If=20 mA 驱动并留有热、电裕度,可获得可靠的长期运行表现。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
