MHLC5019UEGTD 产品概述

一、产品简介

MHLC5019UEGTD 是 MEIHUA(美华)推出的一款 5mm 圆头双色发光二极管(LED),采用插件式封装,内部为共阴极(Common‑Cathode)结构。该器件在单一封装内集成红色与翠绿色两种发光单元,可分别独立驱动,适用于状态指示、面板指示、仪表灯、消费类电子等需要双色显示或混色效果的场合。外形为标准 D=5mm 圆形灯头,发光角度宽广,便于面板观察与均匀照明。

二、主要光电参数

  • 发光颜色:红色(Red)、翠绿色(Emerald Green)
  • 峰值波长(Peak λ):绿 525nm(标称 530nm);红 622nm(标称 632nm)
  • 正向电流(IF):典型工作值 20mA(每色)
  • 正向压降(Vf):绿 ≈ 3.2V;红 ≈ 2.1V(IF = 20mA 时典型值)
  • 最大耗散功率:型号提供 80mW / 120mW 两种额定值(具体以订购型号规格表为准)
  • 发光角度:120°
  • 工作温度范围:-25°C ~ +85°C
  • 封装形式:插件式,D=5mm 圆形灯头,共阴极三脚(公共阴极 + 两个独立阳极)

三、封装与引脚说明

MHLC5019UEGTD 为插件(through‑hole)封装,灯头直径 5mm,灯体为透明/半透明圆形透镜,出光角度为 120°,利于大角度可视。共阴极结构下,通常有三根引脚:一根公共阴极(接地),两根独立阳极分别驱动红色与绿色芯片。该结构便于通过控制单色阳极电流实现双色或混色显示(两色同时点亮可呈现黄/橙色或其他过渡色,视亮度比而定)。

四、典型驱动与应用建议

  • 驱动方式:建议使用恒流源或在电源与阳极之间串联限流电阻进行驱动,避免直接并联至电源导致过流损坏。最大推荐工作电流为 20mA/色。
  • 串联电阻计算公式:R = (Vsup − Vf) / IF
    • 以 5V 电源为例:
      • 绿色:R = (5 − 3.2)V / 0.02A ≈ 90Ω → 常用 100Ω
      • 红色:R = (5 − 2.1)V / 0.02A ≈ 145Ω → 常用 150Ω
    • 以 12V 电源为例:
      • 绿色:R ≈ 440Ω → 常用 470Ω
      • 红色:R ≈ 495Ω → 常用 510Ω / 500Ω
  • PWM 调光:可通过 PWM 控制阳极开关实现亮度调节与色彩混合,注意开关频率需保证人眼无闪烁(>200Hz 通常可接受)。

五、热与可靠性注意事项

  • 温度对光效和波长有影响:高温环境会降低发光效率并使颜色漂移,建议在接近上限温度时适当降额使用(reduce current)。
  • 选择合适的散热与工作环境,避免长期在高湿高温条件下使用。
  • 焊接建议:插件件适合手工焊接或波峰焊,但应控制焊接温度与时间,避免长时间高温作用于灯体与内部焊点,影响可靠性。

六、典型应用场景

  • 面板与按键指示灯、状态指示(开/关、故障/正常等)
  • 仪器仪表、通讯设备、家用电器指示
  • 消费电子、玩具、装饰照明与信号提示
  • 教学与原型开发用灯,因插件封装便于焊接与替换

七、订购信息与注意事项

  • 品牌:MEIHUA(美华)
  • 型号:MHLC5019UEGTD
  • 封装:插件,D=5mm,共阴极双色 LED
  • 采购时请确认所需的最大耗散功率版本(80mW 或 120mW),并核对峰值波长与正向压降等关键参数以满足电路设计要求。
  • 如需更详细的电气特性曲线(光强‑电流特性、相对光通随温度变化曲线等)或三维尺寸图,请向供应商索取完整 datasheet 以便在产品选型与布局时参考。

如需,我可以根据您的供电电压和使用场景,帮您计算推荐限流电阻、给出驱动电路建议或提供封装尺寸草图以便 PCB/面板设计。

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
