MHK2396GGBTD(MEIHUA 美华)产品概述

MHK2396GGBTD 是美华(MEIHUA)推出的一款黄绿色指示型发光二极管(LED),封装为 LED_4.3X9MM_TM、DIP-4(2.54mm 排距) 通过孔封装。该器件适合面板指示、仪表显示、家用电器与消费类电子的状态指示与点亮提示,具有良好的视觉亮度和较窄的发光角度,配以雾状绿色透镜,可获得均匀的视觉效果与较好的光学遮蔽能力。

一、主要参数概览

  • 型号:MHK2396GGBTD
  • 品牌:MEIHUA(美华)
  • 发光颜色:黄绿色
  • 峰值波长:570 nm
  • 正向电流(If):20 mA(典型工作电流)
  • 正向压降(Vf):2.1 V(典型)
  • 光强(Iv):20 mcd(若干测试条件下@20 mA)
  • 发光角度:60°(半值角)
  • 功率:标称 78 mW(规格中给出),典型正向功耗约 Vf×If ≈ 42 mW
  • 工作温度范围:-25 ℃ ~ +85 ℃
  • 透镜:雾状绿色(雾化处理,扩散均匀)
  • 封装:DIP-4,2.54 mm 排距,外形约 4.3 × 9 mm(请以数据表机械图为准)

二、光电特性与解读

  • 峰值波长 570 nm 属于黄绿色波段,视觉敏感度高,在同等电流下能获得较好的可视亮度。
  • 标称光强 20 mcd(20 mA)适合做面板指示与状态提示,不适合远距离照明或大面积背光。
  • 60° 发光角度提供较窄的指向性,结合雾状透镜可兼顾视角覆盖与光斑均匀性。
  • 注意规格中“功率 78 mW”与 Vf×If 的典型耗散(约 42 mW)存在差异,78 mW 更可能为器件最大耗散或绝对最大值,具体请参照厂家完整数据表中的“最大额定值”条目。

三、驱动与电路建议

  • 必须使用限流元件(电阻或恒流驱动器)保护 LED,避免过流。
  • 电阻计算示例(目标 If = 20 mA):
    • Vcc = 5 V:R = (5.0 − 2.1) / 0.02 ≈ 145 Ω,常用 150 Ω、1/4 W 即可。
    • Vcc = 12 V:R = (12.0 − 2.1) / 0.02 ≈ 495 Ω,常用 510 Ω、1/2 W。
  • 电阻功率:以 5 V 情况为例,电阻耗散 P = (Vcc − Vf) × If ≈ 58 mW,使用 1/4 W(0.25 W)电阻有余量;高电压情况下选择更高功率电阻。
  • 建议避免对 LED 施加较高反向电压(多数通用 LED 反向耐压较低),如有可能在电路中并联反向保护二极管或限流措施。
  • PWM 调光时,注意开关频率与占空比对视觉闪烁的影响;频率在几百赫兹以上可避免可见闪烁。

四、封装与焊接注意事项

  • 封装为通过孔 DIP-4,适合手工或波峰/选择性焊接装配。安装时请保证极性正确。
  • 焊接时避免长时间高温作用在塑料部件上,典型建议波峰焊或手工焊接时控制温度与停留时间(请依据厂方焊接说明)。
  • 安装孔与 PCB 布局请参照厂家机械图,2.54 mm 排距便于与标准插针/连接器配合。

五、可靠性与储存

  • 工作温度范围:-25 ℃ ~ +85 ℃,超出该范围会影响发光效率与寿命。
  • 长期高电流或高温条件下,光衰加剧,建议按需降额使用(降低 If 或改善散热)。
  • 储存时请放在干燥、阴凉处,避免高温高湿与强光照射。搬运与安装时注意静电防护(ESD)。

六、典型应用场景

  • 仪表与面板指示灯(电源、状态、工作指示)
  • 家用电器与办公设备的功能提示
  • 消费电子小指示、玩具与手持设备指示
  • 小型信号标识与装饰性指示元件

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
