亿光IR333C 940nm红外发射管产品概述

IR333C是台湾亿光电子推出的标准5mm插件式近红外发射管,聚焦940nm不可见光波长,凭借稳定的辐射性能、宽温适应性及成熟封装工艺,成为光电感应、红外遥控等领域的主流选型元件。以下从核心定位、参数解析、封装设计、应用场景及使用注意事项展开详细说明。

一、产品核心定位与技术优势

IR333C定位于中距离隐蔽型红外发射需求,核心优势体现在三个方面:

  1. 人眼不可见:940nm属于近红外光谱末端,对人眼无视觉感知,避免环境干扰(如夜间补光不暴露设备位置);
  2. 功耗与性能平衡:正向压降仅1.2V,比常规红光LED低30%以上,小电流驱动下仍能保持稳定辐射强度;
  3. 宽温可靠性:-40℃~+85℃的工作范围,覆盖工业、户外等极端环境应用。

二、关键技术参数深度解析

IR333C的核心参数直接决定其适用场景,具体解析如下:

  • 波长940nm:与主流红外接收管(如亿光IRM系列)的响应峰值匹配度达90%以上,减少信号衰减;
  • 正向压降Vf=1.2V:在20mA额定电流下,功耗仅0.024W,适合电池供电的便携设备(如小型遥控器);
  • 辐射强度7.8mW/sr@20mA:该强度可满足5~10米的遥控距离(取决于接收端灵敏度),若采用脉冲驱动(占空比<1%),最大电流100mA时辐射强度可提升至约30mW/sr,进一步延长感应距离;
  • 工作温度范围:低温环境下(如-20℃)仍能保持80%以上辐射强度,高温环境(如+70℃)无明显光衰,符合工业级设备的可靠性要求。

三、封装与可靠性设计

IR333C采用标准圆形5mm插件封装,是行业内应用最广泛的封装形式之一,设计亮点包括:

  1. 焊接兼容性:引脚间距符合IPC标准,可适配手工焊接、波峰焊等多种工艺,焊接温度上限260℃(焊接时间≤3秒);
  2. 封装材质:采用高透光环氧树脂,抗冲击、耐老化,长期使用无发黄现象,确保辐射强度稳定;
  3. 环保与认证:符合RoHS 2.0及REACH标准,无铅无镉,通过亿光内部的高温高湿(85℃/85%RH,1000小时)、冷热冲击(-40℃~+85℃,500循环)测试,可靠性达行业领先水平。

四、典型应用场景说明

IR333C的应用覆盖多个领域,核心场景包括:

  1. 红外遥控系统:电视、空调、机顶盒等家电遥控器的核心发射元件,940nm波长抗环境光干扰能力强,信号传输稳定;
  2. 人体感应模块:配合PIR传感器或红外接收管,用于楼道智能灯、安防摄像头的人体存在检测,隐蔽发射不影响环境美观;
  3. 工业光电开关:流水线物体计数、包装设备定位等场景,近距离感应准确,不受可见光(如车间照明)干扰;
  4. 隐蔽补光:家庭安防摄像头、户外监控设备的夜间补光,940nm不可见,避免暴露摄像头位置,同时提升夜间成像清晰度。

五、选型与使用注意事项

为确保IR333C的稳定工作,需注意以下要点:

  1. 驱动方式:优先采用恒流驱动(如51单片机通过三极管限流),避免电压波动导致电流过大;连续工作电流≤30mA,脉冲电流(占空比<1%)≤100mA;
  2. 存储要求:未开封产品存储于25℃±5℃、湿度≤60%的环境,开封后建议1个月内使用完毕,避免引脚氧化;
  3. 接收端匹配:建议搭配亿光同系列红外接收管(如IRM3638),确保波长、角度(通常±30°)匹配,提升感应距离;
  4. 焊接防护:焊接时避免引脚受热过长,可在引脚根部套热缩管或使用散热片辅助散热。

综上,IR333C凭借成熟的技术参数、可靠的封装设计及广泛的应用场景,成为红外发射领域的高性价比选型,适合对隐蔽性、稳定性有要求的光电系统设计。

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
