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。
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)。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
