MHL4230LRTD 产品概述

一、产品简介

MHL4230LRTD 是由 MEIHUA(美华)推出的高亮度红色发光二极管,采用 4.75mm 直径 DIP 封装,针对室内指示和状态显示等高可视性场合设计。芯片材质为 GaAlInP/GaAs,胶体为雾状红色透镜,光色饱和、抗眩光性能良好,适合对视觉舒适度有要求的应用环境。

二、主要参数

  • 发光颜色:红色
  • 峰值波长:625nm ~ 635nm
  • 正向电压 (Vf):1.8V ~ 2.4V
  • 额定正向电流:20mA
  • 最大功率耗散:80mW
  • 发光强度:50mcd(典型)
  • 发光角度:60°
  • 二极管配置:独立二极管(单发光单元)
  • 透镜颜色/材质:雾状红色环氧树脂
  • 工作温度范围:-40℃ ~ +85℃
  • 封装形式:DIP 直插式,直径 4.75mm

三、关键特性

  • 高亮度、光色纯正:GaAlInP/GaAs 芯片结合雾状透镜,提供平滑的光分布与良好的视觉对比度。
  • 可控光束:60° 发散角便于均匀照明与指示灯设计,避免眩光。
  • 宽温度适用性:-40℃ 至 +85℃ 的工作温度,适用于多数室内及一般工控环境。
  • 易于装配:DIP 直插封装,兼容通用插座和波峰/手工焊接工艺,便于批量生产与维修更换。

四、典型应用

  • 工业/民用电子指示灯、面板指示
  • 仪表、控制台状态显示
  • 家用电器指示与背光
  • 小型标识、信号装置与教育电子项目

五、使用与注意事项

  • 驱动建议:在 20mA 额定电流下工作以保证长期可靠性。例:在 5V 电源下,若按 Vf = 2.0V 估算,限流电阻 R ≈ (5V−2.0V)/0.02A = 150Ω。
  • 功率与散热:注意单只器件最大功率 80mW,长期高流驱动需考虑退化与亮度下降,建议在高温场合降低驱动电流或采取散热措施。
  • 焊接与存储:推荐遵循常规 LED 焊接工艺与防潮要求,避免高温长时间焊接与强光直射,装配与维修过程中注意防静电保护。
  • 环境兼容性:工作温度与环境湿度应在器件规格允许范围内,长期高温高湿会影响使用寿命与光输出。

六、封装与机械信息

产品为标准 4.75mm 直径圆头雾状透镜,DIP 直插引脚,适用于通孔 PCB 和面板安装。独立二极管结构便于并联或单独驱动,具体机械尺寸与引脚间距请参见厂方数据表以确保安装兼容性。

七、订购信息与技术支持

型号:MHL4230LRTD(MEIHUA 美华)
如需样品、批量采购或详细电光参数曲线(光强-电流、波长分布、退化曲线等),建议联系厂商或指定代理商获取完整数据表与质量认证资料,以便在设计中正确选型与可靠验证。

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
