MHLC3029UEGTD 产品概述
一、产品简介
MHLC3029UEGTD 为 MEIHUA（美华）出品的插件式二色发光二极管（3mm 圆形灯头），采用共阴极（共阴）配置，红色与翠绿色双色发光。典型发光角度为 60°，适合面板指示、状态显示与小型信号提示应用。工作温度范围 -25℃ ~ +85℃，结构可靠、装配方便。
二、主要参数
- 灯头类型：3mm 圆形（D=3mm）插件封装
- 发光颜色：红色（波长 622nm）、翠绿色（波长 525nm）
- 正向压降 Vf：翠绿色 ≈ 3.0V，红色 ≈ 2.0V
- 额定功率：80mW；120mW（按元件标称）
- 正向电流：20mA（典型）
- 二极管配置：共阴极（共阴）
- 发光角度：60°
- 工作温度：-25℃ ~ +85℃
三、引脚与接法建议
共阴极结构意味着所有阴极（负极）共用一根引脚，接地（GND）或系统负极；每种颜色的阳极需单独加限流元件（电阻或恒流源）控制电流。推荐电阻按公式计算：R = (Vsup − Vf) / If。示例（If = 20mA）：
- 5V 供电：红色 R = (5 − 2.0) / 0.02 = 150Ω；翠绿色 R = (5 − 3.0) / 0.02 = 100Ω。功率选型 1/4W 即可。
- 12V 供电：红色 R = 500Ω；翠绿色 R = 450Ω，功率建议 1/2W 以上并注意功耗分配。
四、热与可靠性注意
- 静态工作时请勿超过额定正向电流 20mA，过流会缩短寿命或烧毁发光单元。
- 电功率限制（80mW/120mW）需按每色元件分别考虑，长时间高亮应降低电流或使用占空比控制（PWM）。
- 建议在设计时为 LED 提供适当散热路径及避免长期高温环境（建议工作环境低于 85℃）。
五、工艺与安装建议
- 插件式元件，便于手工焊接与波峰焊。手工焊接时焊笔温度建议 ≤ 350℃，焊接时间短于 3s，以免加热损伤。波峰焊温度和时间应参考工厂工艺并做可靠性验证。
- 安装时注意引脚绝缘和弯曲半径，避免应力集中导致断裂或接触不良。
六、典型应用场景
- 仪表与面板指示灯、设备工作状态指示、信号提示、嵌入式开发板与消费电子指示、交通或安全提示小型灯示。
七、选型与订购信息
- 品牌：MEIHUA（美华）
- 型号：MHLC3029UEGTD
购买时确认共阴极连接方式、颜色组合与额定电流，以确保与电路设计匹配。如需更详细的机械尺寸、光强（mcd）或光谱曲线，请向供应商索取完整数据手册。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
