XL-257UBC-L 产品概述

一、产品简介

XL-257UBC-L 是 Xinglight(成兴光)推出的直插式蓝光发光二极管(LED),封装为常见的 5mm 插件型(标注尺寸 2×5×7mm),白色外壳、透明透镜,长引脚设计便于面包板与手工焊接。器件为独立二极管封装,峰值波长 468nm,提供纯净的蓝色指示光,适合仪表、面板指示、背光与电子原型开发等应用。

二、主要规格(典型/范围)

  • 发光颜色:蓝色
  • 峰值波长:468 nm(波长范围 465–470 nm)
  • 正向电流(If):20 mA(标准驱动电流)
  • 正向压降(Vf):3.0 – 3.4 V(在 20 mA 时)
  • 功率:70 mW(额定功率量级)
  • 发光强度:2 cd(在 20 mA 时典型)
  • 发光角度:35°(中等窄发散,方向性较好)
  • 透镜:无色透明透镜,保证颜色纯净且无色偏
  • 二极管配置:独立二极管(单颗 LED)
  • 工作温度:-25 ℃ ~ +85 ℃
  • 封装:插件(直插)5 mm,长脚便于装配与测试

三、产品特点与优势

  • 色纯度高:峰值 468 nm 左右,蓝色表现稳定,适合对色偏敏感的指示或视觉效果场景。
  • 较高方向性:35° 发光角度适合做指示灯或需要较集中光束的应用。
  • 易于装配:标准 5 mm 插件封装、长引脚,适合手工焊接、面包板试验和批量波峰焊/插装。
  • 稳定可靠:额定工作环境宽,能在常见工业与民用温度范围内稳定工作。
  • 通用性强:适配多种驱动与限流方案,便于快速应用于原型与量产。

四、典型电气连接与推荐驱动

  • 常规驱动:建议使用限流电阻或恒流源驱动,避免直接短接电源。
  • 限流电阻计算公式:R = (Vsup − Vf) / If
    • 示例(取 Vf 典型 3.2 V):
      • 5 V 供电:R = (5 − 3.2) / 0.02 = 90 Ω → 取 100 Ω(1/4 W 或更高功率)
      • 12 V 供电:R = (12 − 3.2) / 0.02 = 440 Ω → 取 470 Ω(建议 1/2 W)
  • 恒流驱动:用于高可靠性或多颗串联驱动时优先采用恒流源,能保证亮度一致并延长寿命。
  • 注意:若供电电压接近或低于 Vf(如 3.3 V),无法在 20 mA 下正常驱动,需使用恒流放大或降低目标电流。

五、热管理与可靠性建议

  • 连续工作电流建议不超过 20 mA,长期或高温环境下应进行适当降流(例如 10–15 mA)以延长寿命与降低热应力。
  • 工作温度上限 +85 ℃,高温环境下光衰与正向压降会变化,需在设计时考虑退化与散热。
  • 典型 LED 寿命较长(实务中可达数万小时),但寿命受驱动电流、结温与环境湿度影响显著,设计时应保证合理驱动与散热。

六、装配与使用注意事项

  • 焊接温度:避免长时间高温焊接,手工焊接建议尽量缩短加热时间,避免超过元件的热应力极限。
  • 防静电:LED 对静电敏感,装配与测试时建议采取防静电措施(接地腕带、ESD 工作台)。
  • 机械应力:在修整引脚或弯折引脚时应在距封装一定距离弯折,避免对封装基座产生应力。
  • 存储:长期存储应避免潮湿与强光直射,保持原包装或干燥环境。

七、典型应用场景

  • 面板指示灯、状态指示、开机/工作指示
  • 精密仪器与工业控制面板的信号指示
  • 显示模块、仪表盘背景与点光源应用
  • 教育、电子原型与爱好者项目

八、订购信息与包装

  • 型号:XL-257UBC-L
  • 品牌:Xinglight(成兴光)
  • 封装:插件 5 mm(长脚)
  • 颜色/波长:蓝色 / 465–470 nm(峰值 468 nm)
  • 应在采购时确认批次与光电特性以保证一致性。

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
