MHK1373CGBTD — 黄绿色通孔指示灯概述

一、产品简介

MHK1373CGBTD 是美华(MEIHUA)出品的一款黄绿色(主波长568nm)通孔发光二极管,透镜为雾状绿色,发光均匀柔和。该器件面向通用指示与状态显示场景,工作温度范围宽(-40℃至+85℃),适合工业、仪表及一般消费类产品使用。产品在资料中归类为“未分类”,实际应用中通常作为面板指示灯或状态提示灯。

二、主要参数

  • 发光颜色:黄绿色(568nm)
  • 正向电压 Vf:2.6V(典型)
  • 额定正向电流 If:20mA(最大/常用)
  • 功率:120mW(器件最大耗散功率)
  • 发光强度:50mcd(在额定电流下参考值)
  • 发光角度:80°(中等开角,视角宽)
  • 透镜:雾状绿色
  • 封装:插件通孔,针脚间距 P = 2.54mm
  • 工作温度:-40℃~+85℃

三、电气与光学特性说明

在20mA 驱动下,LED 本体耗散功率约为 Vf × If = 2.6V × 0.02A = 52mW,远低于器件最大额定120mW,留有余量。发光强度 50mcd 在指示类应用中属于可见且不刺目级别,80°光束角利于面板显示与近距离可视覆盖。

常见限流电阻计算举例(以稳压直流源为例):

  • 5V:R = (5 − 2.6)/0.02 = 120Ω,电阻耗散 P = 2.4×0.02 = 0.048W(1/4W 足矣)
  • 12V:R = (12 − 2.6)/0.02 = 470Ω,耗散 P = 9.4×0.02 = 0.188W(建议1/2W)
  • 24V:R = (24 − 2.6)/0.02 ≈ 1.1kΩ,耗散 P ≈ 0.428W(建议1W 以上)

四、封装与安装注意

本品为通孔插件,针脚间距2.54mm,兼容常见面板与插孔处理。安装时注意极性识别(长脚通常为阳极),焊接推荐温度与时长应遵循通孔LED一般工艺:焊接温度不宜过高、焊接停留时间尽量短(波峰或手工焊接遵守设备工艺参数),避免长时间高温导致内封或环氧变色。

五、典型应用场景

  • 仪表、面板状态指示灯
  • 家电与消费电子状态提示
  • 工业控制与信号指示(符合-40℃至+85℃工作温度)
  • 教育与开发板指示灯(通孔便于手工焊接)

六、选型与可靠性建议

  • 若需更长寿命或更低发热,可降额驱动(如 5–10mA)以延长光衰寿命并降低发热。
  • 设计中加入反向电压保护与限流措施,避免过流和反向击穿。
  • 注意 ESD 防护,静电可能损伤LED结。
  • 在高温环境下需关注驱动电流的偏差与光衰,必要时进行温度开路或热沉设计。

七、总结

MHK1373CGBTD 为一款通用性强的黄绿色通孔指示灯,光色辨识度高、视角适中、工作温度范围广,适合各类指示与显示场景。设计时按 Vf=2.6V、If=20mA 的典型值进行电路匹配,并参照上述限流与焊接建议,可获得可靠稳定的指示效果。若有特殊认证或环境要求,建议向供应商确认完整数据手册与可靠性试验报告。

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
