XL-257UYD-L直插发光二极管产品概述

XL-257UYD-L是成兴光(Xinglight)推出的一款直插式黄发黄发光二极管,采用2×5×7mm规格封装,长脚设计便于安装,核心面向电子设备指示、小型照明等低功耗场景,性能参数稳定且适配性强。

一、产品基本定位与核心特征

该LED属于通用型指示类器件,核心特征可概括为:

  1. 黄发黄视觉效果:发光颜色为标准黄光,搭配黄色透镜,发光柔和且辨识度高;
  2. 低功耗稳定输出:额定正向电流20mA下功率仅70mW,无需复杂散热设计;
  3. 宽温适用范围:工作温度覆盖-25℃至+85℃,可适配户外、工业等常规环境;
  4. 直插长脚设计:安装便捷,适合插件式PCB布局,手工焊接友好。

二、关键性能参数详解

1. 发光特性参数

  • 颜色与波长:发光颜色为黄色,峰值波长588nm,波长范围585nm~590nm,属于人眼感知最清晰的黄光波段,避免偏绿或偏红;
  • 发光强度:200mcd(典型值),配合35°发光角度,可在1~3米中等距离清晰识别,既不过亮刺眼也不会过暗看不清;
  • 透镜设计:黄色透明透镜,增强发光集中度,减少光损。

2. 电气特性参数

  • 正向压降(Vf):1.9V2.4V(典型值约2.1V),与常规5V电源适配时,仅需串联150Ω220Ω电阻即可稳定工作;
  • 正向电流(If):额定20mA,最大电流建议不超过25mA(避免过流损坏);
  • 功率:70mW,属于低功耗器件,长时间工作发热小,延长使用寿命。

3. 环境与可靠性参数

  • 工作温度:-25℃~+85℃,可适应冬季低温(如户外设备)和夏季高温(如控制柜内);
  • 寿命:额定电流下连续工作寿命可达5万小时以上,可靠性稳定。

三、封装与物理尺寸

  • 封装类型:直插式(2×5×7mm规格,常见为矩形直插或草帽型变种);
  • 物理尺寸:2mm(厚度)×5mm(宽度)×7mm(高度),小巧紧凑,不占用PCB过多空间;
  • 引脚设计:长脚设计,便于插件焊接时定位,适合手工或自动插件设备。

四、典型应用场景

XL-257UYD-L因性能适配性强,广泛应用于以下场景:

  1. 电子设备指示:家电(空调、洗衣机的电源/状态灯)、仪器仪表(万用表、示波器的功能指示)、开关面板(墙壁开关的夜光指示);
  2. 小型照明与装饰:玩具(发光玩具的眼睛/装饰灯)、小夜灯(低亮度卧室照明)、节日装饰(小型灯串的黄光单元);
  3. 工业控制场景:控制柜指示灯(设备运行/故障指示)、PLC模块状态灯、小型机械的操作提示灯;
  4. 户外辅助标识:低亮度标识牌(楼道指示牌补充照明)、小型警示灯的黄光单元。

五、选型与使用注意事项

  1. 电源匹配:使用时需串联限流电阻,计算公式为:( R=(V_{电源}-V_f)/I_f ),例如5V电源下,( R=(5-2.1)/0.02=145Ω ),建议选用150Ω~220Ω(精度5%)电阻;
  2. 电流控制:避免长时间超过25mA正向电流,防止LED过热衰减或损坏;
  3. 户外防护:LED本身无防水功能,户外使用需配合防水外壳;
  4. 批量适配:成兴光产品参数一致性好,适合中小批量生产,长脚设计便于自动化插件。

六、品牌与产品价值

成兴光(Xinglight)作为国内LED器件制造商,XL-257UYD-L具备以下价值:

  • 成本优势:直插式设计成本低于贴片式,适合预算有限的场景;
  • 可靠性:符合常规LED器件标准,批量产品一致性高;
  • 适配性:宽温范围和低功耗适配多种应用场景,无需额外散热或电源改造。

综上,XL-257UYD-L是一款高性价比直插黄光LED,核心满足通用指示、小型照明的稳定需求,适合手工焊接和批量生产,是电子设计中黄光指示场景的优选器件之一。

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
