XL-IRM638T/TR2 红外遥控接收头产品概述

一、产品基本信息

XL-IRM638T/TR2是Xinglight(成兴光)推出的一款集成化红外遥控接收模块,采用SMD-4P(4引脚贴片) 封装,专为消费电子、智能家居等场景的红外信号接收设计。该模块无需额外外围电路,可直接解调红外遥控信号并输出数字电平,适配多种小型化产品需求。

二、核心电气与性能参数

该接收头的参数覆盖了主流应用场景的核心需求,具体如下:

  • 工作电压:2.7V~5.5V
    兼容3V纽扣电池(便携设备)、5V直流电源(家电/数码产品),无需额外电压转换电路,适配性强;
  • 静态电流:500uA
    低功耗设计,适合对续航敏感的电池供电设备(如智能灯具、迷你遥控器);
  • 接收距离:20m(典型值)
    室内环境下可实现远距离遥控,无需担心操作距离限制;
  • 中心频率:37.9kHz
    匹配市场上80%以上的红外发射端载波频率,兼容性突出;
  • 工作温度:-20℃~+85℃
    可适应低温(冬季户外设备)、高温(厨房电器)环境,环境适应性较好。

三、封装与引脚特性

采用SMD-4P贴片封装,体积小巧(参考同类产品约5.0×4.0×2.5mm),支持自动化贴装生产,能有效节省PCB板空间,适配超薄电视、迷你机顶盒等小型化产品设计。

引脚功能参考同类模块常见定义(需以原厂datasheet为准):

  • 1脚:电源正极(VCC);
  • 2脚:信号输出(OUT,解调后数字信号);
  • 3脚:接地/屏蔽(GND);
  • 4脚:接地(GND)。
    实际应用时需确认引脚排列,避免接反损坏器件。

四、典型应用场景

该接收头的参数特性使其适用于以下场景:

  1. 消费电子终端:电视、机顶盒、DVD播放器等,满足远距离遥控操作;
  2. 智能家居设备:智能灯具、空调、风扇、加湿器等,低功耗适配电池供电的智能模块;
  3. 小型家电:电饭煲、微波炉、空气净化器等,宽温度范围适应厨房高温环境;
  4. 车载影音系统:车载DVD、中控屏等,宽电压兼容车载12V转5V电源,低温稳定工作。

五、性能优势与实用特点

  1. 兼容性强:37.9kHz中心频率匹配主流红外发射器件,无需担心遥控信号不兼容;
  2. 低功耗:500uA静态电流,延长电池供电设备续航(如智能夜灯、便携遥控器);
  3. 抗干扰:内置滤波电路,可抑制日光灯、阳光直射等环境光干扰,提升信号稳定性;
  4. 安装便捷:SMD封装支持自动化贴装,降低生产难度与成本;
  5. 宽温适应:-20℃~+85℃工作范围,覆盖多数室内外使用场景。

六、使用注意事项

  1. 焊接要求:烙铁温度≤260℃,焊接时间≤10秒,避免高温损坏内部芯片;
  2. 强光规避:安装时远离阳光、强LED灯直射,强光环境可搭配遮光罩;
  3. 引脚连接:严格按datasheet确认引脚定义,禁止VCC与GND接反;
  4. 机械应力:焊接后避免施加过大外力,防止引脚脱落或内部电路损坏;
  5. 存储环境:未使用时存于干燥、常温(15℃~35℃)、湿度<60%的环境,避免受潮。

XL-IRM638T/TR2凭借小巧封装、宽适配性与稳定性能,成为消费电子、智能家居领域红外遥控接收的高性价比选择。

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
