XL-2520UBC/TR7 产品概述

一、产品简介

XL-2520UBC/TR7 是 Xinglight(成兴光)推出的一款高亮度蓝色贴片发光二极管,采用 2520 小型封装,适用于空间受限且对亮度和色谱有严格要求的电子设备。该器件峰值波长为 465nm(蓝光),发光强度高,半角发光角窄,适合用于指示、点光源和需要准直光束的场合。

主要参数一览:

  • 发光颜色:蓝色
  • 波长范围:460nm ~ 470nm,峰值波长 465nm
  • 正向压降 (Vf):2.7V ~ 3.2V(典型 20mA 条件)
  • 正向电流(If):20mA(建议驱动电流)
  • 功率:70mW
  • 发光强度:1500 mcd(在标准测试条件下)
  • 发光角度:20°(半角)
  • 封装:2520 贴片(SMT)
  • 载带方式:正贴,TR7 卷带包装
  • 工作温度:-20℃ ~ +85℃

二、主要特性

  • 高亮度、窄发光角:1500 mcd 和 20° 的半角组合,形成集中的光束,便于远距离指示或光学耦合。
  • 可靠的蓝光谱特性:峰值 465nm,适合对蓝光色域有稳定需求的应用。
  • 小型表贴封装:2520 封装便于自动贴装和高密度 PCB 设计。
  • 商用级工作温度范围:-20℃ 到 +85℃,适用于多数工业与消费电子环境。

三、典型应用

  • 指示灯与信号灯(面板指示、指示柱、仪表)
  • 精准定向照明(光学定位、传感器照明)
  • 显示与背光(小型显示模块、按键背光)
  • 汽车/交通信号类的辅助指示(依照相关规范验证后使用)
  • 其他需小体积高亮度蓝光源的电子产品

四、设计与驱动建议

  • 推荐驱动电流为 20mA,以保证亮度与寿命之间的平衡;若追求更长寿命可采用较低电流(如 10~15mA)降低热应力并延长可靠性。
  • 电阻限流计算示例:若电源为 5V,取 Vf=3.0V,则限流电阻 R = (5V - 3.0V) / 20mA = 100Ω。实际设计建议留有余量并考虑温度漂移。
  • 若多颗 LED 并联,建议为每颗 LED 提供独立限流元件以保证均流与故障安全。

五、封装与焊接注意事项

  • 封装形式:2520 表面贴装,卷带(TR7)包装,便于 SMT 贴片机高速贴装。
  • 焊接建议:遵循无铅回流焊规范并以厂商提供的回流曲线为准。为避免因过热或过长回流时间引起封装变形和发光效率衰减,推荐使用标准温度剖面并控制峰值温度和时间。
  • 防潮、防静电:未焊接的元件建议在干燥箱内储存或按厂商给定的 MSL 要求回潮处理后再焊接。

六、可靠性与存储

  • 工作温度范围 -20℃ ~ +85℃,超出该范围可能影响发光效率与寿命。
  • 长期存放应避免高温、高湿及强光照射,建议原包装密封并放置于低温干燥环境。
  • 建议在产品选型与使用前参照完整技术规格书(datasheet)进行温度、湿度及寿命测试,以满足具体应用的可靠性要求。

七、订购信息与资料获取

  • 型号示例:XL-2520UBC/TR7(“TR7” 表示卷带包装)
  • 如需批量采购、样品或详细数据手册(光电特性曲线、回流曲线、尺寸图、可靠性测试数据等),建议联系 Xinglight 或其授权代理商获取最新资料与技术支持。

以上为 XL-2520UBC/TR7 的产品概述与应用建议。实际电路设计与产品认证过程中,请以厂商提供的正式数据手册为准,并根据具体应用环境做充分的验证与测试。

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
