MHPA1010RGBDT 是美华(MEIHUA)出品的一款紧凑型共阳(Common‑Anode)RGB SMD 指示灯,器件主体尺寸约 1.0×1.0×0.6 mm,标称封装尺寸 2.1×1 mm,采用黑色雾状透镜以改善夜间视觉对比和单像素遮挡效果。该器件为 SMD-4P 封装,三色独立驱动,单色正向电流均为 20 mA,常用于小型面板指示、可穿戴产品、微型显示和背光点亮等空间受限场合。
器件为共阳极结构,内部三色共用阳极引脚,三路阴极分离。每色在 20 mA 时为设计工作点,光输出在标称范围内随 Vf 和电流略有波动。绿色光强相对较高(27.6–53.9 mcd),蓝色光强较低(5.9–11.6 mcd),红色居中(17.7–30.0 mcd)。注意 Vf 范围较宽,驱动时应以最坏情况(Vf 最大或最小)进行计算以保证电流稳定。
共阳极接至 Vcc,单色阴极通过限流电阻接地或由驱动器下拉开关控制。限流电阻计算公式: R = (Vcc - Vf) / If
建议为每一路增加适当裕量,优先按最大 Vf 计算确认最坏情况电流不超出规格,并在 PWM 调光时考虑平均功率和热耗。
主体尺寸小,透镜为黑色雾状,适合需要低可视干扰的应用。建议在设计 PCB land‑pattern 时参考厂家数据表以避免应力集中。器件适合自动贴装与回流焊,但请遵循制造商的回流温度曲线与湿敏等级要求(出厂数据表为准)。
该器件对静电较敏感(特别是 G/B 仅 1 kV ESD 公差),生产与调试时必须严格执行 ESD 管控(佩戴接地腕带、使用离子风、EPC 气氛等)。避免超额电流与长期高温运行,延长寿命应控制工作电流、降低环境温度并保证充分散热。
适用于:移动设备指示灯、消费类电子面板指示、微型显示点阵、穿戴设备、仪器仪表微型指示、以及需高对比度小体积 RGB 指示的场合。
在批量采购前建议索取并确认完整数据手册(包含封装图、引脚定义、回流曲线、光度分档与老化条件)。订购时关注光强和色度分档(bin)以保证批次一致性;储存与贴装按厂家建议执行以避免湿气与静电损伤。

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.
