MHK1373CRBDT 产品概述

MHK1373CRBDT 是 MEIHUA(美华)出品的一款红色发光二极管(LED),型号在标称上为 LED-2P_6.35X4.32MM_TM,属于通孔插件式封装元件。该器件以稳定的发光效率、窄谱红光(628nm)和雾状红色透镜外观,适合作为指示灯、面板指示与一般显示用途。

一、产品简介

  • 型号:MHK1373CRBDT
  • 品牌:MEIHUA(美华)
  • 发光颜色:红色(波长 628nm)
  • 封装形式:插件(通孔),P = 2.54 mm(引脚间距)
  • 透镜:雾状红色透镜,能有效扩散光线并降低眩光

二、主要参数

  • 正向电流(IF,最大/额定):20 mA
  • 正向压降(Vf,典型):2.1 V
  • 功率(最大耗散):120 mW
  • 发光强度:40 mcd(在额定条件下典型值)
  • 发光角度:80°(半值角,适中指示视角)
  • 工作温度范围:-40 ℃ ~ +85 ℃

三、电气与热特性(设计要点)

  • 在额定 IF = 20 mA 时,二极管自身耗散功率约为 P = Vf × IF ≈ 2.1 V × 0.02 A = 42 mW,远低于最大耗散 120 mW,但应避免长期接近上限。
  • 推荐串联限流电阻计算:R = (Vs − Vf) / If。示例:
    • 5 V 电源:R ≈ (5 − 2.1) / 0.02 ≈ 145 Ω → 选择 150 Ω。
    • 12 V 电源:R ≈ (12 − 2.1) / 0.02 ≈ 495 Ω → 选择 510 Ω。
  • 长期可靠性受环境温度与结温影响,建议在高温环境下适当降低工作电流以延长寿命。

四、光学特性

  • 波长 628 nm,正红色调,适合状态指示与人眼对比识别。
  • 雾状透镜能扩散光线,提供均匀照明效果并减少光斑,80°视角在面板指示上能保证较好的可视范围。
  • 发光强度 40 mcd(典型),适合近距离指示与一般显示,不适用于需要高亮度远距照明的场合。

五、安装与使用建议

  • 本产品为通孔插件元件,手工或波峰焊安装时注意焊接温度与时间,避免过热导致内部应力或封装变形。
  • 推荐在通孔焊接后留有一定散热路径,若在密集布板或高环境温度下使用,应控制工作电流并保证通风。
  • 运输与存储注意防潮、防尘,避免长时间暴露在强紫外或腐蚀性气体中。常规静电防护(ESD)措施有助于提高良率。

六、典型应用场景

  • 工业与消费类设备的电源/状态指示灯
  • 仪器面板、控制台与家电显示窗口
  • 小型信号指示与装饰性灯光(需低功耗、近距离可视)
  • 汽车内饰或电子模块指示(在符合温度与可靠性要求的前提下)

七、封装与订购提示

  • 封装标识:LED-2P_6.35X4.32MM_TM(请以实物或厂家数据表为准,确认机械尺寸与引脚布局)
  • 订购时核对:颜色(红)、透镜类型(雾状)、电流等级(20 mA)、包装形式(盘带/管装/散装)等。
  • 如需用于关键或长期运行的项目,建议索取并检查厂家完整数据手册(含光电特性曲线、热阻与寿命测试)并做样品验证。

如需,我可以根据您的供电电压与使用环境(工作温度、占空比、预期寿命)帮您计算最佳限流电阻、推荐去耦或驱动方案,并评估替代元件选型。

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
