IRM-3638J7 产品概述

一、产品简介

IRM-3638J7 是台湾亿光(EVERLIGHT)生产的一款红外遥控接收头(插件式、P=2.54mm),面向消费电子遥控、家电控制和各种红外遥控接收应用。该器件采用通孔插件封装,便于手工或波峰/通孔回流装配,适合需要可靠接收和简单驱动的场景。

二、主要参数与特性

  • 工作电压:4.5 V ~ 5.5 V(典型系统 5 V)
  • 接收角度:±35°(对称视场)
  • 封装形式:插件(通孔),引脚间距 P = 2.54 mm
  • 品牌:EVERLIGHT(台湾亿光)
  • 应用消息:用于红外遥控信号接收(常见于 38 kHz 调制系统,具体中心频率请以原厂规格书为准)

三、功能与优势

  • 通用性强:标准 P=2.54 mm 通孔封装,适配常见插针、面包板和传统 PCB 布局。
  • 便于集成:通常输出为经解调的数字信号,可直接被 MCU/单片机读入(具体输出极性与特性请参照原厂数据手册)。
  • 抗光干扰设计:针对环境光与荧光灯抑制优化(一般接收头均包含自动增益控制与滤波电路,但实际性能以数据表为准)。
  • 安装可靠:插件式封装耐用、易更换,适合维修与小批量生产。

四、典型电气与光学建议(设计注意)

  • 电源与滤波:在 Vcc 与 GND 之间放置 0.1 μF 陶瓷旁路电容,近距离焊接以抑制瞬态噪声;必要时并联 4.7–10 μF 电解电容以稳定电源。
  • 输出接口:若外部 MCU 需要拉高,可采用 10 kΩ 左右的上拉电阻;在直接驱动下游电路时注意输出驱动能力与电平兼容性。
  • 极性与引脚定义:不同批次/型号引脚排列可能不同,请在设计前以原厂封装图和引脚图为准,避免直接依赖通用假设。
  • 工作环境:避免将接收窗口直接指向强烈阳光或强光源,减少误触发与灵敏度下降。

五、安装与布局建议

  • 窗口朝向:接收头应面向发射端,避免正对透明塑料或金属阻挡;若产品外壳有红外透镜或窗口,确保材料对 940 nm 波段有良好透过率。
  • PCB 开孔与固定:考虑器件高度与引脚加固,通孔焊接后检查机械牢固度;建议在 PCB 上保留与封装相匹配的 2.54 mm 孔距焊盘。
  • 避免热源:远离大功率发热器件或强电磁干扰源,如电源变压器或高频开关元件。

六、调试与验证要点

  • 信号验证:使用已知的遥控器或示波器观察输出脉冲,确认模块是否正确解调并输出脉冲串(常见为载波包络)。
  • 灵敏度测试:在实际产品外壳与安装位置下测试接收角度与最大有效距离,必要时调整接收口位置或采用小型聚光透镜改善接收范围。
  • 规格核对:在正式投入生产前务必下载并核对 EVERLIGHT 官方数据手册,确认引脚定义、时序、电气极限与环境适应性。

七、总结

IRM-3638J7 以其标准通孔封装、适配 5 V 供电范围和较窄的接收角(±35°)适合精确对向的红外遥控接收场景。在设计中应做好电源滤波、引脚核对与机械安装,实际应用建议结合 EVERLIGHT 官方数据手册进行最终确认与可靠性验证。若需更详细的引脚图、频率响应曲线或光电特性,请参考原厂完整资料或联系代理商索取样片进行评估。

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
