MHDA3631SRBW 3位红色共阳极插件数码管产品概述

一、产品基本定位

MHDA3631SRBW是美华(MEIHUA)电子推出的工业级3位静态数码管,采用插件(DIP)封装设计,以红色LED为发光源,共阳极极性布局。产品核心面向需要清晰数字显示的场景,兼顾显示清晰度、驱动便捷性与环境适应性,是工业控制、仪器仪表、家电及小型电子设备的高性价比显示方案。

二、核心参数详解

1. 显示规格

  • 位数与字符尺寸:3位静态显示,字符高度为0.362英寸(约9.2mm)——中等尺寸既保证近距离清晰识别,又不会因过大占用设备面板空间,适配紧凑式仪器仪表的布局需求;若需小数点显示,部分批次支持可选配置(需提前说明)。
  • 显示视角:典型视角≥120°,从侧面仍可清晰读取数字,满足多方位观察需求。

2. 发光与极性

  • 发光特性:采用红色LED芯片,发光波长约625nm(典型值),红色光对比度高,可有效避免室内强光干扰,且对人眼刺激较小,适合长期观察。
  • 极性设计:共阳极(所有LED段的阳极共用引脚),驱动时仅需控制段脚的低电平信号,电路设计简化,无需复杂的电源切换。

3. 电气与功耗

  • 耗散功率:单管最大耗散功率Pd≤50mW,符合低功耗设计要求,可适配电池供电或低功耗设备。
  • 工作参数:单段工作电压典型值2.0-2.2V,单段工作电流10-20mA(峰值电流≤30mA),直接适配5V主流电源系统,无需额外升压/降压电路。

4. 封装形式

  • 封装类型:标准插件(DIP)封装,引脚间距2.54mm(符合国际标准),引脚数量为10脚(3位共阳极+7段),便于PCB焊接、手工调试及批量生产。
  • 引脚材质:铜质镀锡工艺,焊接牢固性好,不易出现虚焊问题,长期使用可靠性高。

三、结构与可靠性设计

1. 封装材质

外壳采用环氧树脂封装,具有耐冲击、防尘、防潮及抗紫外线老化特性,可适应工业现场的复杂环境(如温度变化、轻微振动),产品使用寿命可达10万小时以上(典型值)。

2. 环境适应性

  • 工作温度范围:-20℃~+70℃,可满足工业设备的宽温需求;
  • 存储温度范围:-40℃~+85℃,便于运输与长期存储。

四、典型应用场景

1. 工业控制设备

如变频器、PLC(可编程逻辑控制器)、伺服驱动器的状态参数显示(频率、转速、温度等),红色显示清晰不刺眼,共阳极驱动适配工业级控制器。

2. 仪器仪表领域

万用表、温度湿度计、计数器、压力表等设备的数字显示模块,0.362英寸字符尺寸兼顾读数便捷与面板紧凑性。

3. 家电控制产品

洗衣机、空调、热水器的参数设置显示(温度、时间、模式等),低功耗特性适合家电长期待机场景。

4. 小型电子设备

电子钟、计时器、计数器等民用设备,插件封装便于手工组装,成本可控。

五、产品优势总结

  1. 显示清晰稳定:红色LED对比度高,字符无重影,120°视角满足多方位观察;
  2. 驱动设计便捷:共阳极极性减少驱动元件数量,可直接对接51单片机、74HC595等主流芯片;
  3. 可靠性耐用性:环氧树脂封装抗环境干扰,插件封装散热好,适合长期连续工作;
  4. 兼容性性价比:引脚布局符合行业标准,可替代同类3位红色共阳极数码管,成本优势明显。

MHDA3631SRBW以实用化设计满足多场景数字显示需求,是传统显示领域的可靠选择。

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
