MHPA3528RGBCT 产品概述

一、产品简介

MHPA3528RGBCT 是美华(MEIHUA)推出的一款高亮度 SMD 3528 封装共阳极 RGB 三色发光二极管。器件体积小(3.5 × 2.8 × 1.85 mm)、配透明无色透镜、视角宽(120°),适合平面光源、指示灯、背光和装饰照明等需要紧凑布局与可调色彩的场合。

二、主要参数

  • 封装:SMD 3528(3.2 × 2.8 mm 系列)
  • 尺寸(长×宽×高):3.5 mm × 2.8 mm × 1.85 mm
  • 二极管配置:共阳极(Common Anode)
  • 波长:R = 622 nm;G = 515–530 nm;B = 460–470 nm
  • 发光强度(IF=20 mA):R = 715–1420 mcd;G = 1120–2250 mcd;B = 285–715 mcd
  • 发光角度:120°
  • 透镜颜色:无色透明
  • 正向电流(IF):R/G/B 均为 20 mA(最大额定)
  • 正向压降(Vf):R = 1.7–2.3 V;G = 2.7–3.3 V;B = 2.7–3.4 V
  • 功率:R ≈ 70 mW;G ≈ 95 mW;B ≈ 95 mW
  • 抗静电能力:R = 2000 V;G/B = 150 V(请按实际批次数据表确认)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、电气特性与驱动建议

  • 共阳极连接方式:将共阳极引脚接至正电源(Vcc),各颜色阴极通过限流电阻或恒流驱动器接地(被拉低以点亮对应颜色)。
  • 推荐恒流或限流电阻计算(按最坏情况下 Vf=max 与目标 IF=20 mA 估算):
    • 以 Vcc = 5.0 V 为例:
      • 红色 R:R = (5.0 − 2.3) / 0.02 ≈ 135 Ω,常用取 150 Ω。
      • 绿色 G:R = (5.0 − 3.3) / 0.02 ≈ 85 Ω,常用取 82–91 Ω。
      • 蓝色 B:R = (5.0 − 3.4) / 0.02 ≈ 80 Ω,常用取 82 Ω。
    • 以 Vcc = 3.3 V 为例:若 Vf 接近 Vcc(尤其 G/B),驱动空间极小,建议使用恒流驱动器或提高供电电压以保证可调余量。
  • 调光方式:建议采用 PWM 调光(频率视应用避免可见闪烁),并对三色分别限流以保持色彩线性与一致性。
  • 热管理:连续高电流会提高结温,影响光衰与寿命,建议在设计中对每通道做适度降额或采用间歇驱动。

四、光学性能

  • 宽视角(120°)适合大面积均匀照明与背光应用。
  • 发光强度范围较宽,适合通过电流或 PWM 精确匹配不同批次及颜色的一致性。
  • 三色通过不同电流组合可获得丰富色域,包括接近白光的混色(需实验校准)。

五、封装与可靠性

  • SMD3528 的标准贴片形式,兼容自动贴片与回流焊工艺。
  • 工作温度 -40 ℃ 到 +85 ℃,适用于一般工业及民用环境。
  • ESD 抗扰度请以出厂数据表为准,不同颜色通道对静电敏感度可能不同,生产与装配过程中应严格采用防静电措施。

六、典型应用

  • 仪表/面板指示灯、状态显示
  • 背光与装饰照明(家具、标识、玩具)
  • 可编程灯条、像素点阵与舞台小型照明
  • 消费类电子产品的情景照明与氛围灯

七、安装与注意事项

  • 建议按典型回流焊曲线焊接,避免对灯体产生机械应力。
  • 使用前应做批次光色配对与电流校准,尤其在做白光或色温稳定性设计时。
  • ESD 保护必须到位,装配人员佩戴防静电手环并采用接地台面。
  • 切勿长期超过额定电流/功率,以免加速老化或失效。

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
