XL-IRM0038C-38B 产品概述
一、产品简介
XL-IRM0038C-38B 是成兴光（Xinglight）推出的一款高灵敏度红外遥控接收头（IRM），封装为 SMD-3P，尺寸约 5×5mm。该器件针对遥控信号接收及解调应用优化，适用于家电遥控、机顶盒、智能家居及玩具等领域。器件工作电压范围宽（2.7V～5.5V），兼容多种系统电源电压。
二、主要参数
- 工作电压：2.7V ～ 5.5V
- 工作电流：典型 300 μA（静态或工作模式请参照具体应用）
- 接收距离：最大可达 12 m（取决于发射端功率与环境）
- 中心频率：37.9 kHz（针对常见遥控载频）
- 耗散功率（Pd）：250 mW
- 工作温度：-40 ℃ ～ +85 ℃
- 封装：SMD-3P，尺寸约 5×5 mm
上述参数为器件典型工作条件下的参考值，实际值受环境与电路影响。
三、功能特性
- 内置载波滤波与解调电路，直接输出解调后的数字脉冲信号，便于 MCU 或专用解码芯片接收处理。
- 对 37.9 kHz 载波有较好选择性，抑制环境光与低频噪声干扰。
- 低功耗设计，静态与工作电流低，有利于电池供电产品的续航。
- SMD 小封装便于自动贴装与批量生产。
四、典型应用
- 电视、机顶盒、DVD/蓝光播放器遥控接收模块
- 家用电器（空调、风扇等）遥控系统
- 智能家居控制器、红外桥接器
- 红外遥控玩具与便携设备
五、引脚与安装建议
- 引脚排列通常为 VCC、GND、OUT（建议在 PCB 布线与丝印时确认封装标记），输出为解调数字信号（通常为低电平有效），具体逻辑请参考生产商资料。
- 建议在 VCC 与 GND 之间并联 0.1 μF 的去耦电容，靠近器件引脚布置，以减少电源噪声对接收灵敏度的影响。
- 为获得最佳接收性能，接收窗口应避免被金属遮挡，天线（透镜）方向应对准红外发射源。封装高度小，适合贴片加工，但需注意极端机械应力。
六、使用注意事项
- 遵守最大耗散功率 Pd=250 mW 限制，避免长时间在高温或高功率条件下工作。
- 安装与焊接过程中注意 ESD 防护，避免静电损伤内部敏感电路。
- 工作温度范围 -40 ℃～85 ℃，在极端温度下性能可能变化，关键应用建议进行温度验证。
- 接收距离受发射端光强、发射角度、环境光与遮挡物影响，设计时应留有裕量。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
