EVERLIGHT 19-21/BHC-AP1Q2/4T(0603)产品概述

一、产品简介

EVERLIGHT(台湾亿光)型号 19-21/BHC-AP1Q2/4T 为一颗高亮蓝色贴片发光二极管(SMD),采用微小 0603 封装。该器件发光波长集中于 464.5nm~476.5nm,峰值 468nm,透镜为无色透明,发光角度约 100°,适合空间受限场合的指示与背光应用。器件额定正向电流为 20mA,单颗功率上限 75mW,工作温度范围 -40℃ 到 +85℃。

二、主要性能特点

  • 发光颜色:蓝色(峰值 468nm,典型 464.5–476.5nm)
  • 正向电压 Vf(典型):3.3V
  • 额定正向电流 If:20mA
  • 单颗最大耗散功率:75mW
  • 封装:0603(约 1.6mm × 0.8mm)
  • 透镜:无色透明,发散角约 100°
  • 工作环境温度:-40℃ ~ +85℃
  • 二极管配置:独立单二极管,便于逐颗驱动与点亮控制

三、典型电气与光学参数(使用注意)

  • 正向电压与电流关系:在 If = 20mA 时 Vf ≈ 3.3V,器件耗散功率约 66mW(P = Vf × If),低于 75mW 的功耗限制,常规工作在 20mA 为安全区间。但长时间高温下应适当降流以延长寿命。
  • 光谱:适合需要深蓝至蓝色显示的指示或点光源场合。
  • 发光角度与透镜:100° 宽角度配合透明透镜,有较好的均匀性与可视面积,但非聚光型。

四、驱动与电阻选型建议

为确保稳定与安全,建议使用恒流驱动或在电源与 LED 串联限流电阻。常见电源下的限流电阻示例(目标 If = 20mA):

  • 5V 电源:R = (5.0 − 3.3) / 0.02 ≈ 85Ω → 选择 82Ω 或 100Ω,电阻功率 ≈ 0.03W(1/8W~1/4W 足够)
  • 12V 电源:R = (12 − 3.3) / 0.02 ≈ 435Ω → 430Ω 或 470Ω,电阻功率 ≈ 0.17W(选 1/4W 或更高)
  • 3.3V 电源:由于 Vf ≈ 3.3V,直接并联限流电阻无足够压降,不建议直接使用;可采用恒流驱动或升压驱动电路。

注意:电源波动、器件 Vf 公差及温升都影响实际电流,恒流驱动能提供最稳定与可靠的亮度控制。

五、热管理与可靠性

  • 器件最大功耗 75mW,典型工作(20mA)耗散约 66mW,靠近上限时需注意 PCB 热阻与周围热源。建议在 PCB 设计中为 LED 引脚和焊盘提供适当铜箔面积以利散热。
  • 环境温度升高会降低可允许电流,应根据工作温度对正向电流进行降额(consult 数据手册获取详细 derating 曲线)。
  • 常见应力来源:过电流、长期高温回流、过度机械应力(贴装/修整)会影响寿命与光衰。

六、典型应用场景

  • PCB 面板指示灯、功能状态指示
  • 仪表/便携设备背光与按键背光
  • 装饰灯、标识与信号指示
  • 光学传感/检测中蓝色光源(需依据具体光学需求确认)
  • 工业与消费电子设备,适用温度范围广泛

七、装配、搬运与储存注意事项

  • 贴片焊接:遵循厂商推荐的回流温度曲线(常见 Pb-free 峰值约 240℃ 左右),避免过长高温暴露;回流前建议在贴装后尽快回流,减少吸湿回流破坏。
  • 防潮包装:小封装 LED 对潮湿敏感,建议按厂商建议的防潮等级(MSL)和干燥包装存放,开启后在规定时间内回流安装。
  • ESD 防护:蓝色 LED 及其驱动电路对静电敏感,搬运与贴装操作需佩戴防静电手环、使用接地工作台及防静电包装。
  • 机械应力:避免针头、镊子直接压迫透镜,防止导致光学或封装损伤。

八、选型与替代建议

该 0603 蓝色 LED 以体积小、视角宽、峰值光谱稳定为特点。若需更高亮度或更低 Vf 可考虑其他封装(1210、0805 等)或不同型号;若需更严格光色一致性或更高温度耐受性,请参照亿光完整数据手册并与供应商确认批次光学分级(BIN)与可靠性报告。

备注:本文为产品概述与常规设计建议,具体电气极限、回流曲线、光学分级与可靠性数据请以亿光官方数据手册为准,并在量产前进行样品验证与可靠性测试。

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.
