XL-IRM0038C 红外遥控接收头产品概述
一、产品简介
XL-IRM0038C 是成兴光（Xinglight）推出的一款 SMD 红外遥控接收头，封装为 SMD-3P（4×4mm）。该器件针对常见家电与消费电子遥控控制场景设计，能够接收并处理载波频率附近的红外遥控信号，用于微控制器或解码器前端的信号输入。
二、主要参数
- 工作电压：2.7V ~ 5.5V
- 工作电流：典型 250 μA（低功耗）
- 接收距离：典型 10 m（视发射功率与环境光照而定）
- 中心频率：37.9 kHz（针对 38 kHz 遥控编码族优化）
- 耗散功率 Pd：250 mW
- 工作温度：−40 ℃ ~ +85 ℃
- 封装：SMD-3P，尺寸 4 × 4 mm
三、核心特性
- 低功耗：工作电流约 250 μA，适合电池供电设备。
- 频率匹配：37.9 kHz 中心频率，对常见 38 kHz 遥控器具有良好灵敏度与抑干扰能力。
- 小型化封装：4×4mm SMD-3P，有利于自动贴装与高密度 PCB 布局。
- 宽温度范围：适应工业级环境温度要求。
四、典型应用
- 电视、机顶盒、音响等家庭影音遥控接收端。
- 空调、风扇、智能家居控制面板。
- 玩具、遥控灯具及便携式红外控制设备。
五、安装与使用注意事项
- 建议在电源引脚靠近放置 0.1 μF 去耦电容以抑制电源噪声。
- 接收器与红外发射器保持一定角度与距离，避免正对强光源或太阳直射。
- PCB 开孔或天线方向应保证接收窗口无遮挡。
- 遵循静电防护规范，避免 ESD 损伤敏感输入。
六、封装与引脚建议
SMD-3P 封装便于贴片加工，建议查阅器件实际封装图（datasheet）以确认焊盘尺寸与推荐 PCB land pattern，确保焊接可靠性与热散能力。
七、可靠性与环境指标
工作温度覆盖 −40 ℃ 至 +85 ℃，耗散功率 250 mW，适合多数消费与工业应用场景。设计时应考虑周边器件热源与散热路径以避免超出 Pd 限值。
八、设计提示
- 输出端通常为数字脉冲信号，后接 MCU 时可使用中断或定时采样方式解码。
- 在强光或荧光灯环境下可能出现误触发，应在系统层面加入滤波或重试机制。
- 若要求更远接收距离或更强抗干扰能力，可考虑配合光学透镜或改进外壳窗口设计。
如需进一步的引脚定义、电气特性曲线或封装图纸，可提供 datasheet 索取或告知具体应用场景以便给出更精细的选型与电路设计建议。

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.
