MHLA3029UEGTC 产品概述

一、产品简介

MHLA3029UEGTC 是美华(MEIHUA)推出的一款双色指示灯器件,采用 SIP-3 直插封装(引脚间距 2.54mm),外壳为无色透明透镜,便于光学分布和二次透镜配合。器件内置红色与翠绿色两种发光元件,适用于面板指示、仪表、家电和消费电子等需要双色指示或状态显示的场景。

二、主要特点

  • 发光颜色:红色(Red)、翠绿色(Emerald Green)
  • 典型正向电流:20 mA(建议工作电流)
  • 正向压降(Vf):
    • 红色:1.8 V ~ 2.2 V
    • 翠绿色:2.7 V ~ 3.3 V
  • 功率(典型/最大工作功耗估算):
    • 红色:约 45 mW
    • 翠绿色:约 70 mW
  • 峰值波长 / 波长:
    • 红色:峰值 629 nm,波长约 622 nm
    • 翠绿色:峰值 517 nm,波长约 523 nm
  • 发光强度(Iv):
    • 红色:约 650 mcd
    • 翠绿色:约 1000 mcd
  • 发光角度:80°
  • 透镜颜色:无色透明,光学一致性好
  • 工作环境温度:-30 ℃ ~ +90 ℃

三、电气与光学参数说明

  • 正向电流(If):20 mA 为推荐典型值,可根据亮度需求和寿命要求在 1~20 mA 范围内调整,但建议通过限流电阻或恒流驱动器控制电流,避免长期过流。
  • 正向压降(Vf)范围依据颜色不同而异,设计电源和限流元件时应按相应颜色的 Vf 范围取值或参照样品实测数据。
  • 发光强度(mcd)表示在主方向上的亮度输出,翠绿色通常在人眼响应上感觉更亮,因此在同等电流下绿光的输出(1000 mcd)高于红光(650 mcd)。
  • 发光角度 80° 表示器件具有较宽的视角,适合面板指示和可视范围较大的应用。

示例限流电阻计算(以单色驱动、5V 电源为例):

  • 红色(取 Vf = 2.0 V):R = (5 V − 2.0 V) / 20 mA = 150 Ω,电阻功率 P = I^2·R ≈ 0.06 W(取常规 1/4W 电阻足够)。
  • 翠绿色(取 Vf = 3.0 V):R = (5 V − 3.0 V) / 20 mA = 100 Ω。

对较高电压或并联多灯,需相应增大电阻或采用恒流驱动,以保证长期可靠性。

四、封装与机械信息

  • 封装形式:SIP-3 单列直插,针脚间距 2.54 mm,适配标准 PCB 插孔和面板安装方式。
  • 透镜:无色透明,便于与外部二次光学件配合(如遮光帽、扩散罩)。
  • 结构利于快速插装和波峰/回流焊工艺后的机械固定,但在回流焊时建议参考厂商焊接曲线,避免高温长时间作用于 LED。

五、使用建议与注意事项

  • 驱动方式:优先使用恒流源或在每一路串联限流电阻,避免以直接恒压方式驱动导致电流过大。
  • PWM 调光:支持 PWM 调光以实现亮度控制和双色混光,但 PWM 频率应高于人眼可感知频闪(通常 ≥ 200 Hz)。
  • 热管理:尽管单颗功耗较小,仍建议在长期点亮或密集布局下关注散热路径与 PCB 散热设计,避免器件长期处于高温环境影响寿命。
  • 环境与存储:工作温度范围 -30 ℃ ~ +90 ℃,储存与搬运应避免潮湿和强酸碱环境;建议在常温干燥下保存并遵守防静电操作规范。
  • 焊接与清洗:焊接时避免过高温度及过长时间;清洗溶剂应选择对 LED 无腐蚀性的溶剂,避免浸泡导致透镜污染或光学性能下降。

六、典型应用

  • 面板与机箱指示灯(电源/状态/报警)
  • 仪表、医疗设备中的状态显示
  • 家用电器(微波炉、洗衣机等)指示
  • 消费电子与玩具(双色提示)
  • 工控及通信设备状态指示

七、采购与定制建议

  • 采购时请确认所需颜色、发光强度等级(bin)与封装引脚配置(若有公共阳极或公共阴极要求),并向供应商索取样品进行光电参数验证。
  • 如需特殊光学方向、扩散处理或低功耗驱动方案,可与美华(MEIHUA)技术支持沟通定制需求。

总结:MHLA3029UEGTC 以其双色指示、透明透镜与标准 SIP-3 封装,提供可靠的指示解决方案。合理的限流驱动与良好的散热与安装规范,能确保器件在宽温范围内稳定工作,满足多种工业与消费类应用的需求。

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.
