MHPA3528CRGBCT(MEIHUA 美华)产品概述

MHPA3528CRGBCT 是美华(MEIHUA)推出的一款高亮度共阳极三色 RGB SMD 发光二极管,封装为 SMD3528(尺寸约 3.5 × 2.8 mm),适用于面板指示、状态显示、背光与装饰照明等需要小体积、多色可控光源的场合。该器件采用无色透明透镜、宽视角设计,颜色纯正、光强稳定,支持贴片回流焊工艺,工作温度范围宽(-40℃ 至 +85℃),便于批量生产与工业级应用。

一. 主要光学与电气参数

  • 发光颜色与波长

    • 蓝 (B):460 nm ~ 470 nm
    • 绿 (G):515 nm ~ 530 nm
    • 红 (R):622 nm(典型)
  • 发光强度(在典型测试条件下)

    • 红 (R):225 mcd ~ 450 mcd
    • 蓝 (B):285 mcd ~ 715 mcd
    • 绿 (G):1120 mcd ~ 2250 mcd
  • 发光角度:120°(宽视角,均匀可视)

  • 透镜颜色:无色透明(颜色纯正、无需滤色)

  • 正向工作电流(各色):典型 20 mA(建议最大驱动电流为 20 mA)

  • 正向压降 Vf(在 20 mA)

    • 红 (R):1.7 V ~ 2.3 V
    • 绿 (G):2.7 V ~ 3.3 V
    • 蓝 (B):2.7 V ~ 3.4 V
  • 功率(单色通道,典型/最大工况参考)

    • 红 (R):约 70 mW
    • 绿 (G):约 95 mW
    • 蓝 (B):约 95 mW

二. 封装与机械特性

  • 封装型号:SMD3528(3.5 × 2.8 mm)
  • 裸露外观:无色透明透镜,平面顶面,便于光学耦合与外观一致性
  • 安装方式:表面贴装(正贴),兼容自动贴片与回流焊流程
  • 工作温度:-40 ℃ ~ +85 ℃(适合室温与工业环境使用)

三. 引脚与驱动建议(共阳极配置)

  • 器件为共阳极(common anode)结构:所有正极共用一个引脚,三个负极分别为 R/G/B 通道。
  • 常见驱动方式
    • 将共阳极接至 VCC(例如 3.3 V 或 5 V 等合适电源),用三路低侧开关(NPN、NMOS 或 专用 LED 恒流驱动器)分别控制 R、G、B 通道的电流。
    • 推荐使用恒流驱动或在每通道串联限流电阻以限制电流至 ≤20 mA。
  • 电阻选择示例(以 VCC = 5.0 V、保证不超过 20 mA 为目标,按各色最小 Vf 来计算)
    • R 通道(Vf_min = 1.7 V):R ≥ (5.0 − 1.7) / 0.02 ≈ 165 Ω → 推荐 180 Ω
    • G 通道(Vf_min = 2.7 V):R ≥ (5.0 − 2.7) / 0.02 ≈ 115 Ω → 推荐 120 Ω
    • B 通道(Vf_min = 2.7 V):同 G 通道,推荐 120 Ω
  • 调光与色彩控制:支持 PWM 调光以实现亮度与颜色混合;建议 PWM 频率高于可见闪烁阈值(>1 kHz)以避免肉眼闪烁。

四. 可靠性与静电保护

  • 抗静电能力(参考)
    • 绿 (G):150 V
    • 红 (R):2000 V
    • 蓝 (B):150 V
  • 说明:实际 ESD 抗性受测试方法与包装状态影响较大。尽管红色通道显示较高的抗静电值,整个器件仍应在符合 ESD 管理(ESD-safe)环境中操作与贴装,包含佩戴防静电腕带、使用防静电台面与包装等。

五. 典型应用场景

  • 消费电子:指示灯、状态显示、功能背光
  • 工业与通信设备:面板指示、报警/通知指示
  • 商显与装饰照明:多色标识、氛围照明与装饰条灯
  • 小型多色显示模块、玩具与智能家居指示

六. 设计与使用注意事项

  • 驱动电源与限流:为保证长期稳定与一致性,推荐使用恒流驱动 IC 或为每通道精确设计限流电阻,避免因 Vf 波动导致电流过大或色度漂移。
  • 热管理:单颗功率不大,但在高填充密度 PCB 或高环境温度下,应考虑散热与间距,避免长期高温加速衰减。
  • 焊接工艺:兼容常规回流焊流程,建议按元件供应商或行业标准设定回流曲线,避免超温或多次回流影响性能。
  • 储存与搬运:保持干燥包装,避免受潮回流时产生焊接缺陷;贴装时注意避免正负极反接。

本产品以其小体积、宽视角与高亮度输出适合多场景集成。选型时请结合实际工作电压、驱动方式与环境温度进行详细电气与热设计,以获得稳定一致的色彩与寿命表现。如需更详细的封装尺寸图、回流曲线或典型光谱曲线,请向供应商索取完整数据手册。

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
