MHPC3528CRGBCT 产品概述

一、产品简介

MHPC3528CRGBCT 是 MEIHUA(美华)推出的一款 SMD3528 封装的共阴极 RGB 发光二极管。器件采用正贴(SMT)贴装方式,透明无色透镜、120° 发光角,适合指示灯、面板背光、装饰照明及小型显示模块等对色彩混合与可控亮度有要求的场合。

二、光学与光谱特性

  • 发光色谱:三色 RGB,峰值波长分别为:G 515 nm、B 460 nm、R 630 nm。标称波段为 B:460–470 nm、G:515–530 nm、R:621 nm(参考)。
  • 发光强度(典型/范围):R 225–450 mcd;B 285–715 mcd;G 1120–2250 mcd(在正向电流 If=20 mA 条件下)。
  • 发光角度:120°(宽视角,适合面光源及扩散应用)。

三、电气性能与热特性

  • 推荐工作电流:R/B/G 均为 20 mA(单色驱动时的典型值)。
  • 正向压降(Vf 范围):R 1.7–2.3 V;G 2.7–3.3 V;B 2.7–3.4 V(随电流和温度略有变化)。
  • 标称功率(厂方给值):B 110 mW、R 60 mW、G 100 mW(如需精确热设计,请参照完整数据手册)。
  • 工作温度范围:-40 ℃ ~ +85 ℃。

计算示例(用于电阻选型):

  • 若电源为 5 V,驱动 R(Vf≈2.0 V,If=20 mA):R = (5–2.0)/0.02 ≈ 150 Ω;
  • 驱动 G/B(Vf≈3.0 V,If=20 mA):R = (5–3.0)/0.02 ≈ 100 Ω。

注意按温度升高进行电流降额,延长器件寿命并降低色漂。

四、可靠性与抗静电

  • 抗静电能力(厂方给值):G / B ≈ 150 V,R ≈ 2000 V。三色管脚的 ESD 耐受能力存在明显差异,红色通道抗静电能力远高于绿蓝通道。
  • 建议在 PCB 装配与调试过程中采取严格的防静电措施(佩戴腕带、使用防静电工作台、避免对裸管脚直接放电)。

五、封装与装配建议

  • 封装:SMD3528,透明透镜,顶发光或侧发光(请依据样片确认朝向)。
  • SMT 工艺:适用常规回流焊流程,建议遵循 SMT 元器件的吸湿与预烘烤规范以避免湿气引起的焊接缺陷。
  • 布局建议:共阴极(共阴脚)结构在 PCB 设计上便于将公共负极连接到地,单色输出端串联限流电阻或恒流驱动器以保证一致性。

六、应用场景与设计要点

  • 典型应用:状态指示、词条背光、微型面板、APP 控制的装饰照明、颜色混合演示等。
  • 调光建议:采用 PWM 驱动可实现宽范围的亮度控制与色彩混合;不同颜色的亮度响应曲线差异较大(绿色亮度显著更高),在配色时需通过占空比与电流配比进行校准。
  • 电气保护:建议在每个通道使用单独限流电阻或恒流源;对抗静电较弱的通道(G、B)应在输入端增加 TVS 或 RC 抑制网络以提升可靠性。

七、使用注意事项

  • 避免超过最大正向电流与最大结温;长期高温或过流会导致亮度衰减与色移。
  • 由于各色通道的 Vf 与亮度差异,量产时建议挑选或做颜色/亮度分选(binning)以保证成品一致性。
  • 如需进一步的电学、光学典型波形与回流曲线,请索取完整器件数据手册。

总结:MHPC3528CRGBCT 以其 SMD3528 小型封装、宽视角与高亮度绿光为主要优势,适合多种小型彩色指示与背光场合。在电路设计上需重视通道差异(Vf、亮度与 ESD 能力)并采取相应的限流与防静电措施,以获得稳定且可控的颜色表现。

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
