MHK4212CGTD 产品概述

一、产品简介

MHK4212CGTD 是 MEIHUA(美华)出品的一款黄绿色发光二极管,封装为插件式 DIP-8(2.54mm 间距),透镜为雾状绿色,适合面向宽视角指示、面板显示及仪表背光等应用。该元件以稳定的发光颜色和良好的可视角度为特点,便于在各种工业与消费类设备中作为状态指示或光源单元使用。

二、主要参数

  • 发光颜色:黄绿色
  • 峰值波长:568 nm
  • 正向电压(Vf):约 2.0 V
  • 额定正向电流(If):20 mA
  • 额定功率:78 mW(器件标称)
  • 发光强度:10 mcd
  • 发光角度:130°(宽视角、雾状透镜)
  • 工作温度:-25℃ ~ +85℃
  • 封装:DIP-8,2.54 mm 引脚间距,插件式

三、特性与优势

  • 宽视角(130°)与雾状透镜设计,指示面均匀、可见性好,适合大视野观察位置。
  • 峰值 568 nm 的黄绿色在昼夜环境下对人眼敏感度较高,提示明确而不刺眼。
  • 插件式 DIP-8 封装便于手工焊接与插拔维护,适合原型开发与小批量生产。
  • 工作温度范围广,能满足一般工业与民用环境要求。

四、应用场景

  • 仪表、面板指示灯(电源、状态、故障指示)
  • 消费电子背光与指示(家电、音响等)
  • 工业控制设备与测试仪器
  • 教学样品、原型开发与电子玩具

五、使用建议与注意事项

  • 驱动与限流:建议采用恒流源驱动,若用串联限流电阻计算(以 5 V 电源为例):R = (Vs − Vf) / If = (5 − 2.0) / 0.02 ≈ 150 Ω,所需电阻功率至少取 0.25 W。
  • 功耗说明:器件标称功率为 78 mW,但单颗在 If=20 mA、Vf≈2.0 V 时的电耗约 Vf×If ≈ 40 mW,仍应按厂商额定值与 PCB 散热条件设计。
  • 焊接与存储:通过孔插件式,建议回流前手工或波峰焊工艺温度遵循厂方焊接规范,防止高温超过器件耐受;存储时避免潮湿、强光及静电。
  • 防静电措施:作为半导体器件,装配时应采取基本的防静电与防污染措施以保证可靠性。
  • 环境与可靠性:在高温、高湿或剧烈震动环境下使用前建议做可靠性验证。

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
