MHP5050RGBDT 产品概述

MHP5050RGBDT 是美华(MEIHUA)推出的一款 SMD5050 封装 RGB 发光二极管,体积为 5.0 × 5.0 × 1.55 mm,内部为独立三色二极管设计,配备白色雾状透镜,实现柔和、均匀的漫射效果,适用于指示、装饰及背光等多种场景。

一、主要电光参数

  • 波长范围(典型峰值):红 R 617–627 nm(峰值 632 nm);绿 G 515–525 nm(峰值 518 nm);蓝 B 465–475 nm(峰值 468 nm)。
  • 发光角度:绿 120°、蓝 120°、红 115°(透镜为雾状,出光柔和)。
  • 正向电流(If):每色 20 mA(独立驱动)。
  • 正向压降(Vf):R 1.95–2.35 V;G 2.75–3.35 V;B 2.75–3.35 V。
  • 功率(典型):R 120 mW;G 95 mW;B 95 mW。
  • 抗静电能力(典型):R 2000 V;G、B 各 1000 V。
  • 工作温度:-40 °C 至 +85 °C。

二、结构与封装特点

MHP5050RGBDT 采用标准 SMD5050 封装,尺寸紧凑但三色独立,便于在 PCB 上按需布线与驱动。白色雾状透镜有助于色光混合及均匀出光,适合近距观测时减少像点感。

三、典型应用场景

  • 状态指示与信号提示(工业设备、家电面板)。
  • RGB 装饰照明与氛围灯(橱窗、家具、舞台小景)。
  • 平面背光与标识照明(按键、LOGO、信息牌)。
  • 小型屏显与可编程像素点阵(需按色彩校准)。

四、驱动与设计建议

  • 每色单独驱动,建议使用恒流源或在开关电源/MCU 输出端串联限流电阻。示例:5 V 供电驱动红色(取 Vf≈2.2 V,If=20 mA),R ≈ (5−2.2)/0.02 ≈ 140 Ω,常用 150 Ω 标准值。
  • 长时间点亮时应考虑功耗与散热,避免 PCB 局部过热。尽量保证铜箔散热路径以降低结温,提高寿命与亮度稳定性。
  • 调光建议采用 PWM(频率 ≥ 1 kHz)以避免肉眼可见闪烁,并注意驱动器的上升/下降时间匹配。

五、焊接与可靠性注意

  • 采用回流焊工艺组装时,请遵循 J-STD-020 标准及厂方推荐回流曲线,峰值温度一般不超过 260 °C;为延长使用寿命建议按组件承受能力优化回流参数。
  • 存储与操作需防静电,装配与测试时佩戴防静电手环、使用离子风机,避免对灯珠发生静电击穿。
  • 推荐在湿度敏感等级(MSL)要求下按厂家建议的防潮回流时间窗口操作。

六、测试与配套建议

  • 量产检验建议测量正向电压、正向电流及颜色坐标(如需严格色温/色品位控制),并在典型工作温度下做光学衰减测试。
  • 若用于精确色彩还原场合,需对 RGB 三色进行相对亮度与色坐标校准,或选用恒流驱动并结合软件伺服调节。

MHP5050RGBDT 以其独立三色、雾状透镜与紧凑封装,适合需要柔和漫射及小尺寸布局的 RGB 应用。具体回流参数与可靠性测试建议参照美华提供的产品技术手册。

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
