ASMT-UWB1-NX3A2 产品概述

一、产品简介

ASMT-UWB1-NX3A2 是 Broadcom(博通)推出的一款高亮度冷白色贴片 LED,封装为 2-PLCC,带有黄色漫射透镜(Yellow Diffuse),面向指示、背光和通用照明显示应用。该器件在行业应用中以稳定的光效、较宽的发光角度和良好的视觉均匀性著称,适合对外观一致性和亮度有较高要求的场景。

二、主要电学与光学参数

  • 发光颜色:冷白色(Cool White)
  • 正向压降(Vf):典型 3.2 V(在 IF = 20 mA)
  • 正向电流(IF):标准工作电流 20 mA(建议采用恒流驱动)
  • 发光强度:2300 mcd(典型值)
  • 发光角度:120°(宽视角,视野均匀)
  • 透镜颜色:黄色漫射,能改善发光面观感并降低点光源刺眼感

三、光学特性与外观效果

黄色漫射透镜会使冷白光在出光面上更均匀,降低镜面眩光,视觉上更加柔和,适用于面板指示、标识灯和边缘照明。120° 的大角度保证了广域可视性,减少了对准角度的依赖。

四、驱动与热管理建议

建议采用恒流源驱动以保证亮度与色温一致性,20 mA 为典型驱动电流。避免长期超额驱动,必要时可通过降额使用(降低电流)延长寿命。封装面积小,散热通道有限,建议在 PCB 设计时增大铜箔散热面积并预留热焊盘以降低结温,确保环境温度和结温在器件规格允许范围内。

五、PCB 与加工注意事项

2-PLCC 封装适合常规 SMT 回流工艺。推荐依据博通的封装/焊盘推荐图设计焊盘,保证焊膏量均匀,避免过多焊膏导致倾斜;回流焊温度和曲线请参照厂方推荐的峰值温度与时间窗。器件有防潮等级要求,长期暴露空气中可能需按 MSDS/库存建议进行防潮处理和回流前烘烤。

六、可靠性与防护

在设计中应考虑静电防护(ESD),安装和测试环节使用接地防护措施。器件在高温、高湿或化学腐蚀性气氛下可能加速光衰,应用场景如户外或高温环境需采取封装防护或选择对应级别产品。

七、典型应用场景

适合仪表指示灯、家电面板、工业控制面板、按键背光、信息显示条及消费电子的指示/装饰照明等场合,尤其需要均匀面光和宽视角的设计中表现良好。

备注:以上内容基于器件典型参数与封装特性给出设计建议。实际设计请参照 Broadcom 官方数据手册与应用说明书,以获取完整的最大额定值、热阻和可靠性测试数据。

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
