MHDC2052SRBW 5位共阴极红色数码管产品概述

美华(MEIHUA)推出的MHDC2052SRBW是一款专为紧凑空间设计的5位共阴极红色LED数码管,兼具低功耗、高辨识度与易驱动性,广泛适配电子仪表、家电控制等场景,是小尺寸数字显示的优选器件。

一、核心参数与基本定位

MHDC2052SRBW的核心参数清晰匹配小型显示需求:

  • 显示规格:5位集成显示,字符高度0.2英寸(≈5.08mm),字符宽度≈3.0mm,视觉识别清晰且不占空间;
  • 电气特性:共阴极极性(公共端为阴极),单段耗散功率≤50mW(总功耗随点亮段数线性变化),红色LED正向电压Vf≈1.8-2.2V,单段工作电流典型值15mA;
  • 封装形式:插件DIP-13封装,引脚间距2.54mm,适配标准PCB设计;
  • 发光特性:红色发光,峰值波长≈625nm,低光环境下辨识度高,寿命≥10万小时。

二、关键性能特点

  1. 小尺寸高集成:0.2英寸字符+5位一体设计,减少PCB布局复杂度,适合手持设备(如万用表)、小型计数器等紧凑场景;
  2. 驱动友好:共阴极结构可直接由单片机IO口驱动(需串联限流电阻),无需额外驱动芯片,降低系统成本;
  3. 低功耗可靠:单段50mW功耗满足电池供电需求,LED芯片采用美华自研封装,抗老化、抗冲击,长期使用稳定性强;
  4. 易焊接适配:DIP插件封装适配手工焊接、波峰焊,引脚间距符合行业标准,兼容性好。

三、典型应用场景

MHDC2052SRBW因尺寸小、功耗低,广泛应用于:

  • 小型电子仪表:万用表、温湿度计、转速计的数字显示;
  • 家电控制面板:洗衣机定时、微波炉倒计时、空调温度显示;
  • 消费类电子:电子钟、计数器玩具、小型计算器;
  • 工业辅助设备:传感器读数显示、小型电机状态监控。

四、封装与引脚说明

  • 封装类型:DIP-13(双列直插13引脚);
  • 引脚功能(参考官方 datasheet): 1-5脚:第1-5位公共阴极(K1-K5); 6脚:段a(阳极)、7脚:段f(阳极)、8脚:段e(阳极)、9脚:段d(阳极)、10脚:段c(阳极)、11脚:段g(阳极)、12脚:段b(阳极); 13脚:小数点(DP,阳极);
  • 封装尺寸:长×宽×高≈30mm×10mm×5mm(可根据实际需求微调)。

五、使用注意事项

  1. 限流电阻配置:每段阳极需串联限流电阻,公式:R=(Vcc - Vf)/If(Vcc=5V时,R≈200Ω,避免过流损坏LED);
  2. 驱动方式选择:静态驱动(每个位公共阴极接IO,段接IO)适合低刷新率;动态驱动(5个公共阴极轮流拉低,段同时输出数据)适合高刷新率,减少IO占用;
  3. 焊接防护:手工焊接温度≤260℃(单引脚≤3秒),波峰焊温度≤240℃(≤5秒),需接地防静电;
  4. 存储环境:温度-40℃~+85℃,湿度≤85%RH,避免强光直射与机械冲击。

六、美华品牌优势

美华电子专注LED显示器件研发10余年,MHDC2052SRBW具备:

  • 一致性好:批量产品亮度、波长偏差≤5%,显示均匀;
  • 供货稳定:年产能充足,满足小批量到大规模订单需求;
  • 环保合规:符合RoHS、REACH等环保标准,适配出口产品。

该器件凭借高性价比与可靠性能,成为小型数字显示领域的主流选择。

BOM matching & alternatives

BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.

Electronic component sourcing availability dashboard with ESD-protected samples

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
