成兴光XL-3216IRC-940贴片红外发光二极管产品概述

一、产品基本信息

成兴光(Xinglight)推出的XL-3216IRC-940是一款1206封装的贴片红外发光二极管,属于近红外发射器件。该型号针对常规红外应用场景优化,核心波长集中在940nm左右,具备体积小、功耗低、发射角度宽等特点,广泛适配民用及工业级电子设备的红外控制、感应等功能需求。

二、核心电气参数解析

1. 正向压降(Vf):1.2V~1.6V

红外LED的正向压降低于可见光LED(如红光LED约1.8V~2.2V),表示器件正向导通时的电压范围。实际应用需匹配限流电阻,确保工作电压落在该区间,避免过压/欠压导致性能异常。

2. 耗散功率(Pd):45mW

器件允许的最大总功耗,实际工作时需注意“电流×电压”乘积不超过45mW。长期超功耗会导致芯片过热,缩短寿命甚至损坏。

3. 波长范围:939nm~946nm

属于人眼不可见的近红外光谱,是红外遥控、接近感应的主流波长——多数红外接收器件(如光敏二极管、接收头)对940nm左右的红外光响应最灵敏,兼容性强。

4. 辐射强度:2mW/sr

衡量红外光发射能力的关键参数(sr为立体角单位)。2mW/sr的辐射强度可满足常规室内5~10米有效作用距离,适配电视、空调遥控器等民用场景,兼顾小型感应模块的近距离需求。

5. 正向电流(If):30mA

额定正向工作电流,脉冲驱动时可适当提高峰值电流,但需控制平均电流≤30mA,避免芯片过载。

6. 直流反向耐压(Vr):5V

器件能承受的最大反向电压,超5V可能导致芯片击穿,电路设计需避免反向过压(如串联反向保护二极管)。

7. 视角:120°

发射视角宽达120°,红外光覆盖范围大,无需严格对准接收端即可有效工作(如遥控器角度偏移仍能控制设备),提升使用便利性。

三、封装与物理特性

采用1206贴片封装(公制尺寸3.2mm×1.6mm),具备以下优势:

  • 体积小巧:适配高密度电路板,适合智能手环、小型遥控器等便携设备;
  • 贴片工艺:可通过自动化SMT生产线焊接,生产效率高,适合批量制造;
  • 抗振性强:封装引脚与电路板贴合紧密,优于插件式LED,适配移动设备场景。

四、典型应用场景

结合参数特性,该器件主要应用于:

  1. 红外遥控设备:电视、空调、机顶盒遥控器的发射端,匹配940nm接收头实现无线控制;
  2. 接近感应模块:配合红外接收管组成接近开关,用于自动门、电梯感应、手机距离传感器;
  3. 安防补光:夜间监控摄像头的红外补光(人眼不可见,不干扰环境);
  4. 智能家居控制:智能灯、窗帘等设备的红外控制模块;
  5. 隐蔽指示:设备待机状态的红外指示(人眼不可见,避免干扰)。

五、使用注意事项

  1. 电流限制:正向工作电流≤30mA,脉冲驱动时控制平均电流≤30mA;
  2. 焊接规范:回流焊温度≤260℃(持续≤10秒),手工焊接温度≤350℃(持续≤3秒),避免高温损坏芯片;
  3. 反向保护:避免反向电压超5V,可串联反向保护二极管;
  4. 环境温度:工作温度范围-40℃~+85℃,极端温区需评估性能稳定性;
  5. 抗干扰:户外应用需配合940nm滤光片,避免阳光红外成分干扰。

六、总结

XL-3216IRC-940是一款性价比突出的常规红外LED,参数覆盖民用及工业级基本需求,1206封装适配小型化设计,940nm波长兼容性强。适合批量应用于红外遥控、感应等场景,是电子设备红外发射功能的常用选择。

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.
