MHLA5319URGBDWT 产品概述
一、产品简介
MHLA5319URGBDWT 为 MEIHUA（美华）出品的高亮度共阳极三色 LED，封装为 5mm 圆形插件（D≈4.9mm，整体高度约 8.7mm）。白色雾状透镜提供柔和光散射效果，适用于面光均匀的指示与装饰场景。型号标识出色光学和电气参数，适合标准 PCB 或面板安装。
二、光学与电气参数
- 发光色及峰值波长：红 R 618–629nm；绿 G 517.5–525nm；蓝 B 450–463nm。
- 发光角度：70°（典型），配合雾状透镜获得较均匀的发光面。
- 正向电流（IF）：R/G/B 均为 30mA（典型驱动值）。
- 发光强度（Iv）：G 1500mcd；R 600mcd；B 300mcd（在额定电流下）。
- 正向压降（Vf）：R 2.0–2.6V；G 2.8–4.0V；B 2.9–4.0V。
- 功率：G/B 120mW；R 85mW。
- 抗静电能力：各色均达到 2kV（典型），装配时仍需采取防静电措施。
- 工作温度范围：-40℃ ~ +85℃。
三、封装与引脚形式
本件为插件式（通孔）LED，共阳极结构，便于在单电源下以电流下拉驱动各色通道。白色雾状透镜与 5mm 圆形灯头设计适合面光效果和视觉舒适性的应用。
四、驱动与应用建议
- 驱动方式：共阳极意味着把共阳脚连接到正电源，单独通过限流电阻或恒流下拉（低侧开关）控制各色阴极。建议使用恒流驱动或为每色配置合适电阻以保证亮度一致。
- 调光：推荐 PWM 调光以实现宽范围亮度控制与色彩混合；选用频率高于人眼可感知范围以避免闪烁。
- 热管理：在接近额定电流长期点亮需关注散热与环境温度，避免超出单色功率限制影响寿命与光衰。
- 应用场景：指示灯、面板显示、小型背光、装饰照明、信号标示、教育与创客项目等。
五、装配与注意事项
- 焊接：按通用插件 LED 焊接工艺进行，手工或波峰焊装配时控制焊接温度与时间以防损伤。
- ESD 防护：虽标称 2kV 抗静电，仍建议在生产与装配过程中采取防静电手环、导电台垫等措施。
- 参数匹配：实际设计中请基于最不利 Vf（最大值）与电流来计算限流电阻或驱动设定，预留余量以保证长期可靠性。
- 测试：量产前做全色通道一致性与色坐标测试，尤其在要求精确配色的应用中。
MHLA5319URGBDWT 以其高绿光强度与雾状漫射效果，适合需均匀面光且易于驱动的多色指示与装饰应用。设计时按上述电气与热工注意事项选型与布线，可获得稳定的光学表现与可靠寿命。

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.
