MHK33147CGBTD 产品概述

一、产品简介

MHK33147CGBTD 为 MEIHUA(美华)出品的发光二极管(LED),采用 DIP-6 2.54mm 通孔封装。发光颜色为黄绿色(中心波长 568nm),雾状绿色透镜带来柔和扩散光效,适用于面板指示与一般状态显示场合。

二、关键参数

  • 发光颜色:黄绿色(568nm)
  • 正向电压 Vf:2.6V(典型)
  • 正向电流 If:20mA(标称工作电流)
  • 额定功率:78mW(器件最大额定功率);典型工作功耗 ≈ 2.6V×20mA = 52mW
  • 发光强度:30mcd(IF=20mA)
  • 发光角度:60°
  • 透镜:雾状绿色
  • 工作温度:-25℃ ~ +85℃

三、电气与光学特性说明

在标称条件(If=20mA)下光强约 30mcd,60° 出光角适中、方向性明确。若需延长寿命或降低热升,建议降流到 10–15mA 使用,光强相应下降但可靠性提高。请使用恒流源或串联限流电阻驱动,常见电阻计算:R = (Vsup − Vf) / If;例如 5V 电源时 R ≈ (5−2.6)/0.02 = 120Ω。

四、封装与机械特征

DIP-6(2.54mm)通孔封装,便于插拔与人工或波峰焊装配。雾状透镜能抑制眩光并改善观察角度一致性。安装时注意极性标识与引脚间距,确保 PCB 孔径与镀层处理匹配,便于长期可靠接触。

五、应用场景

适合各类状态指示、面板灯、仪器指示灯、消费电子指示、低亮度指示条以及教育与原型开发。雾化透镜尤其适用于需要柔和视觉效果的场合。

六、设计与使用建议

  • 驱动:推荐恒流驱动或串联限流电阻;若 PWM 调光,频率建议 >100Hz 以避免可见闪烁。
  • 热管理:尽量控制环境温度并降低过大电流;长时间高温工作将加速光衰。
  • 寿命:在推荐电流下 LED 寿命可达数万小时,实际取决于温度与驱动方式。
  • 焊接:遵循通用 LED 焊接工艺,避免长时间高温直烙,预热后短时高温焊接;若不确定,请按厂家焊接说明操作。

七、存储与可靠性

避免潮湿与阳光直射,常温干燥保存;搬运装配时采取静电防护措施。工作环境应控制在额定温度范围内以保证长期稳定性。

八、订购与备注

型号:MHK33147CGBTD;品牌:MEIHUA(美华);封装:DIP-6-2.54mm。选型时请确认所需光强与颜色容差,并参考采购方或制造商提供的完整数据手册以获得详细的电气极限、机械尺寸与焊接规范。

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
