MHT151RGBCT 产品概述

一、产品简介

MHT151RGBCT 是美华(MEIHUA)推出的高性能 RGB 三色发光二极管,采用 1206 小封装并以反贴(反向贴装)方式设计,透明透镜保证了纯净的出光颜色与宽广的视角,适用于细小 PCB 尺寸的全彩指示与背光场合。器件针对常见指示与显示应用优化了亮度和功耗表现,便于在有限空间实现色彩混合。

二、主要电气与光学参数

  • 波长范围:红 R 616–630 nm;绿 G 515–530 nm;蓝 B 460–470 nm
  • 峰值波长:R 632 nm;G 518 nm;B 468 nm
  • 正向电流(If):R/G/B 均为 20 mA(典型驱动)
  • 正向压降(Vf):R 1.7–2.4 V;G 2.5–3.6 V;B 2.5–3.6 V
  • 发光强度(If=20 mA):R 112–285 mcd;G 450–900 mcd;B 112–285 mcd
  • 发光角度:130°(半值角)
  • 功率(单色):R/G/B 均为 95 mW(最大耗散参考)
  • 抗静电能力(ESD):R 2000 V;G 1000 V;B 1000 V
  • 工作温度范围:-40 ℃ 至 +85 ℃

三、封装与机械特性

  • 封装型号:1206,体积小、适合集成密集型电路
  • 贴装方式:反贴(需要按 PCB 设计反向管脚与焊盘)
  • 透镜颜色:无色透明透镜,有利于直接色彩输出与混色控制
  • 品牌:MEIHUA(美华)

四、典型应用

  • 面板指示灯、状态显示
  • 小型背光和按键照明
  • RGB 指示与色彩提示(需要 PWM 校准混色)
  • 仪表、消费电子、智能家居指示灯
  • 装饰性小型照明与信号灯

五、设计与使用建议

  • 驱动方式:推荐恒流驱动或在串联限流电阻的稳压电路中使用,单色典型 If=20 mA;为延长寿命及提高可靠性,可考虑 50–80% 的电流降额策略。
  • PWM 调光:建议使用高频 PWM(>200 Hz)进行亮度与色彩控制,避免低频闪烁。
  • 热设计:尽管封装小巧,仍需关注 PCB 散热与功率限制,单色最大功耗不超过 95 mW。
  • 焊接与贴装:反贴封装要求 PCB pad 与过孔设计匹配,建议遵循厂家 PCB 布局建议并采用合适的回流焊工艺;装配前做好 ESD 防护。
  • ESD 防护:器件对静电敏感,尤其绿蓝色,装配与测试过程中应使用带电阻的防静电手腕带、工作台及防静电包装。

六、可靠性与注意事项

  • 推荐在产品开发阶段进行温度、湿度和寿命加速评估,确认在目标应用环境(-40~+85 ℃)下的光衰与电特性稳定性。
  • 储存与搬运请遵循湿敏等级与防静电规范,避免潮湿和强静电冲击导致性能退化或损坏。
  • 采用前请核对样品参数与批次一致性,量产时建议建立来料检验项目(亮度、Vf、波长、外观)。

总结:MHT151RGBCT 以 1206 反贴小封装、宽视角与较高的绿光亮度为特点,适合对空间、色彩与驱动效率有要求的指示与背光场景。合理的电流控制、良好的 ESD 保护与 PCB 热设计是发挥其性能与寿命的关键。

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
