MHL3214UBDWT — 发光二极管(蓝光)产品概述

一、产品简介

MHL3214UBDWT 是美华(MEIHUA)推出的一款高性价比蓝色发光二极管,3mm 圆形插件封装,雾状白色透镜设计,发光波长约 470nm,呈现纯净蓝色光效。适用于状态指示、面板背光、消费电子和各类指示灯等场合,兼具良好的视觉效果与可靠性。

二、主要参数

  • 发光颜色:蓝色(波长 470nm)
  • 灯头类型:3mm 圆形(D=3mm)雾状白色透镜
  • 正向电流(If):20mA(常规工作)
  • 正向压降(Vf):约 3.5V
  • 最大功率:110mW(器件最大耗散能力)
  • 在 20mA 条件下典型功耗:约 70mW(Vf×If)
  • 发光强度:250mcd(典型)
  • 发光角度:60°
  • 工作温度范围:-25℃ ~ +85℃
  • 封装形式:插件(Through-hole)
  • 品牌:MEIHUA(美华)
  • 型号:MHL3214UBDWT

三、外观与光学特性

雾状白色透镜能有效扩散点光源,使亮度更加均匀,减少眩光感,适合做指示灯或需要柔和视觉效果的应用。60°的发光角度在保持指向性的同时,也能覆盖较宽视角,配合 3mm 小型灯头适用于面板密集布局。

四、电气与热特性建议

在常规设计中建议工作电流不超过标称 20mA,以保证器件寿命与稳定性。器件最大耗散能力为 110mW,实际应用时需考虑功耗与散热条件;例如在 20mA、Vf≈3.5V 时,器件功耗约为 70mW,留有余量可提高可靠性。高温环境下应适当降额使用,避免长期满载工作导致光衰或失效。

五、应用场景

适用场合包括但不限于:

  • 仪器仪表与面板指示灯
  • 电子玩具与消费电子设备状态指示
  • 交通信号小指示灯与装饰照明
  • 教学与DIY 电子制作项目

六、封装、安装与注意事项

  • 插件式 3mm 封装,便于手工或波峰/插件自动化安装。
  • 建议在焊接时避免对透镜及引脚施加过大机械力;尽量使用适度温度与时间的焊接工艺以防损伤器件。
  • 存储时应置于干燥、避光的环境,避免长时间潮湿、高温或强光直射,以延长使用寿命。
  • 电路设计中建议并联多个 LED 时采用限流电阻或恒流驱动,避免因单点失效影响整个串并联网络。

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
