MHL5013UBDWT(MEIHUA 美华)5mm 蓝光 LED 产品概述

一、产品简介

MHL5013UBDWT 是 MEIHUA(美华)出品的高亮 5mm 插件蓝光发光二极管,典型命名 LED_D5X8.6MM_TM。该器件采用透明无色透镜、窄光束设计,峰值波长约 470nm(典型波长 468nm),在 20mA 驱动下表现出优秀的发光强度与方向性,适用于各类指示及需要点光源的照明场合。

二、主要参数(典型/最大)

  • 发光颜色:蓝色
  • 峰值波长:470nm(中心波长 468nm)
  • 正向电流(If):20mA(典型工作点)
  • 正向压降(Vf):3.2V(典型)
  • 最大功率耗散:120mW(器件最大限值)
  • 典型工作功耗:Vf × If ≈ 3.2V × 20mA = 64mW
  • 发光强度:9300 mcd(典型 @20mA)
  • 发光角度:30°(半值角,窄光束)
  • 透镜:无色透明
  • 封装:插件(D = 5mm,长度参考型号 D5×8.6mm)
  • 工作环境温度:-25℃ ~ +85℃

三、电气与光学特性解析

该 LED 在 20mA 下为高亮窄角点光源,9300mcd 的亮度与 30° 的发光角,适合用作指示灯、光学定位和需要远距指示的场合。典型正向压降 3.2V,实际值会随温度和驱动电流略有变化。器件额定最大功耗 120mW,应避免长期在接近极限的功耗下运行;典型工作时实际耗散约 64mW。

四、驱动建议与限流计算

为保证稳定与寿命,建议采用恒流驱动或在电源端串接限流电阻。限流电阻计算:

  • R = (Vs - Vf) / If 示例:
  • 5V 电源:R = (5 - 3.2) / 0.02 = 90Ω → 取 91Ω(1/8W 或 1/4W 均可),功率 P = I^2·R ≈ 0.036W
  • 12V 电源:R = (12 - 3.2) / 0.02 = 440Ω → 取 470Ω(1/4W 推荐),功率 P ≈ 0.176W(建议使用 ≥1/4W 电阻)

如需高精度亮度控制或多颗串并联驱动,优先考虑恒流源或专用 LED 驱动芯片;PWM 调光效果良好,但需保证频率高于人眼可感知范围并做好电磁兼容设计。

五、热管理与环境适配

工作温度范围为 -25℃~+85℃,高温条件下正向压降会下降但光输出随温度升高可能降低。长期可靠性需注意热堆积与散热,插件式安装时保证良好通风或采用散热结构。当环境温度升高时,应适当降低驱动电流(参照厂商降额曲线)以延长寿命。

六、安装与焊接建议

  • 插件封装,安装时避免对灯体施加过大机械应力。
  • 手工或波峰焊:建议焊接温度不超过 260℃,焊接时间尽量短(典型手工焊 3–5s)。
  • 焊后勿立刻弯折引脚,避免应力集中导致光学结构损伤。
  • 取料、装配过程中注意防静电,LED 对静电敏感,应使用接地工具与防静电工作区。

七、典型应用

  • 仪器面板及设备指示灯
  • 消费电子指示与状态显示
  • 精密定位与指示光源
  • 小型光学模块与信号指示
  • 装饰及点状照明应用

八、注意事项与可靠性要点

  • 避免长时间高电流运行或超额定功率工作,推荐在 20mA 或更低电流下使用以延长寿命。
  • 避免反向过压与脉冲性高压,必要时串联二极管或限流措施保护。
  • 高亮蓝光直视可能造成不适或视觉疲劳,请在设计上避免直接注视强光源。
  • 出货及存储应避免潮湿、高温和强光直射,建议密封包装并在常温干燥环境中保存。

本产品以其高亮度、窄发光角和稳定的电光特性,适合需要点状强指示性的多种电子设备,实际选型时建议参考完整数据手册并与供货商确认温升、曲线与包装尺寸等详细参数。

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
