MHK2396RRBTD 产品概述

MHK2396RRBTD 是美华(MEIHUA)出品的一款高可靠性红色指示型发光二极管(LED),具有雾状红色透镜和宽视角特性,适用于面板指示、仪表、家电和各类状态指示场合。本产品以稳定的电光参数和插件式封装(引脚间距 P=2.54mm)方便手工或波峰焊安装,适配常见电子设计与装配流程。

一、主要电光参数

  • 发光颜色:红色(波长 628nm)
  • 正向电压(Vf):1.8V ~ 2.4V
  • 额定正向电流:20mA(推荐连续工作电流)
  • 最大功率:80mW(建议不要长期接近最大值)
  • 发光强度:约 150mcd(典型,If=20mA 条件下)
  • 发光角度:100°(雾状透镜,漫射均匀)
  • 透镜颜色:雾状红色
  • 工作温度范围:-40℃ ~ +85℃

二、封装与机械特性

  • 封装形式:插件(穿孔安装)
  • 引脚间距:P = 2.54mm,兼容常见面板与 PCB 布局
  • 品牌:MEIHUA(美华)
  • 描述分类:未分类(通用指示用 LED)

三、驱动与使用建议

  • 推荐连续正向电流不超过 20mA,长期使用应适当降额以延长寿命。
  • 计算限流电阻示例(取 Vf 近似 2.0V):
    • 3.3V 供电:R ≈ (3.3−2.0)/0.02 ≈ 65Ω → 选 68Ω,1/4W 可用;
    • 5V 供电:R ≈ (5−2.0)/0.02 ≈ 150Ω → 选 150Ω,1/4W 可用;
    • 12V 供电:R ≈ (12−2.0)/0.02 ≈ 500Ω → 选 560Ω,建议 1/2W 或更大功率电阻。
  • 可采用恒流驱动以获得恒定亮度和更好的可靠性;避免直接并联多个 LED 不加限流。

四、热管理与可靠性

  • 虽然功耗较低,但在高环境温度下需适当降额使用;长期在高温环境(接近 +85℃)下工作会影响寿命与光衰。
  • 建议 PCB 设计时为 LED 留出适当散热路径并避免热源集中。

五、焊接与储存建议

  • 推荐使用常规插件焊接工艺,避免长时间高温暴露。
  • 手工焊接或波峰焊时,建议控制焊接温度与时间以保护封装和内芯结构。
  • 储存时避免潮湿、强光及腐蚀性气体,建议原包装密封保存。

六、典型应用

  • 仪表与面板指示灯、状态指示、按键背光、家用电器指示、通信设备状态显示、工业控制面板等。

总结:MHK2396RRBTD 以其稳定的红色发光(628nm)、雾状漫射性质和宽视角(100°)为优势,适合需要柔和、均匀指示光的应用场景。设计时注意限流与热管理,可获得长期稳定可靠的性能表现。

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
