MHK2310GEBTD 产品概述

一、主要参数与标称性能

MHK2310GEBTD 是 MEIHUA(美华)推出的一款插件式指示型LED,适用于面板指示与一般照明指示场合。主要电光参数如下:

  • 发光颜色:红色、绿色
  • 峰值波长:红 630 nm,绿 570 nm
  • 正向电流(If):典型 20 mA(最大按规格书限制)
  • 正向压降(Vf):1.8 V ~ 2.4 V(随颜色和电流有小幅变化)
  • 最大功率:80 mW(单颗器件功率耗散上限)
  • 发光强度:绿色约 150 mcd,红色约 25 mcd(典型值,测量条件通常为 If=20 mA,Ta=25℃)
  • 发光角度:100°(典型半角,适合宽视角指示)
  • 透镜:雾状绿色透镜 / 雾状红色透镜(漫射效果良好,减少眩光)
  • 工作温度范围:-40 ℃ ~ +85 ℃
  • 封装形式:插件式,针脚间距 P = 2.54 mm(便于面板安装和通孔焊接)

二、产品特性与优势

  • 色彩稳定:红绿双色选择,峰值波长典型且稳定,适用于状态指示与色彩区分要求的应用。
  • 漫射透镜:雾状透镜能有效扩散光线,视角宽(100°),避免点光源直射,提高可视舒适性。
  • 通用驱动:20 mA 正向电流为常见驱动条件,可直接与通用驱动电路或限流电阻配合使用,便于工程实现。
  • 宽工作温度:-40 ℃ 至 +85 ℃ 的工作区间,适用于室内及工业环境的多数应用场景。
  • 插件封装:2.54 mm 间距通孔封装,便于手工焊接或波峰焊,适用于快速样机开发与批量生产。

三、典型应用场景

  • 面板状态指示:电源、运行/故障指示、模式指示等。
  • 仪器仪表:电表、控制面板的状态反馈。
  • 消费电子:家电前面板、遥控器指示灯(作为状态提示)。
  • 工业设备:PLC、控制柜、设备指示灯(在环境温度和震动不超过器件规格的前提下)。
  • 教学与制作:实验板、原型开发、DIY 电子项目。

四、驱动与使用要点

  • 限流电阻计算:常用直流电源下建议串接限流电阻保护 LED。计算公式 R = (Vsup - Vf) / If。示例(以 5 V 电源、If=20 mA 为例):
    • 绿灯(Vf 约 2.0 V):R ≈ (5.0 - 2.0) / 0.02 = 150 Ω
    • 红灯(Vf 约 1.8 V):R ≈ (5.0 - 1.8) / 0.02 = 160 Ω
  • 功率核算:单颗耗散功率 P ≈ Vf × If,典型约 36–40 mW,远小于器件标称 80 mW 上限,但长期工作建议适当余量与散热考虑。
  • 驱动方式:可采用恒流驱动以获得稳定亮度与延长寿命;对于脉冲驱动,应控制峰值电流和占空比,避免超出热极限。
  • 极性识别:插件 LED 通常长脚为阳极(正极),焊装时注意方向以防接反。

五、可靠性与储存建议

  • 防静电:LED 为半导体器件,建议在装配与测试时采取基本的防静电措施(接地、腕带、防静电台面)。
  • 焊接与检修:建议参照厂家焊接指导进行通孔焊接,避免长时间高温加热导致封装变形或光学性能退化。
  • 储存环境:避免潮湿、高温与强光直射,建议在干燥、常温环境中保存,长期存放前按厂家建议进行防潮处理(如干燥包)。

六、选型与采购建议

在选型时,请依据实际亮度需求(绿 150 mcd 与红 25 mcd 为典型值)、安装空间、工作电流与环境温度等因素综合判断。MHK2310GEBTD 适合对宽视角、漫射显示有要求的指示场合;如需更高亮度、不同封装或波长,请咨询美华提供的完整型号系列或索取详细数据手册以获取温度特性曲线、光强分布图及最大额定值等关键信息。

总结:MHK2310GEBTD 是一款结构简单、使用便捷、适用面广的插件式指示LED,适合面板指示与一般电子装置的状态提示需求。若需样品或批量采购,可向 MEIHUA 授权经销渠道索取样品与技术支持。

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
