XL-2012IRC-940 红外发射二极管产品概述

一、产品基本定位

XL-2012IRC-940是成兴光(Xinglight) 推出的0805贴片式近红外发射二极管,核心功能为发射940nm波长的不可见红外光,适配小型化、低功耗电子设备的设计需求,在红外遥控、近距离感应等场景中应用广泛。其紧凑封装与稳定性能,成为消费电子、智能家居领域的常用器件。

二、核心性能参数详解

1. 光学特性

  • 发射波长:939nm~946nm(近红外波段,人眼完全不可见,隐蔽性强,避免干扰视觉感知);
  • 辐射强度:2mW/sr(可满足5~10米内红外遥控、感应的信号强度需求,适配日常使用场景);
  • 视角:120°(宽辐射角度,覆盖范围广,无需精准对准接收端即可触发功能,提升使用便利性)。

2. 电学特性

  • 正向压降(Vf):1.2V~1.6V(低正向压降,降低驱动电路功耗,适配3.3V/5V常见电源,无需额外升压/降压电路);
  • 耗散功率(Pd):45mW(最大允许功耗,需避免过流导致器件发热老化);
  • 正向电流(If):30mA(额定工作电流,驱动电路需通过限流电阻严格控制电流不超过此值);
  • 直流反向耐压(Vr):5V(反向电压上限,避免反向过压击穿器件,需在电路中增加反向保护)。

3. 环境适应性

  • 工作温度:-40℃~+85℃(宽温范围,可适应户外、车载、工业级等复杂环境,可靠性高)。

三、封装与尺寸优势

XL-2012IRC-940采用0805贴片封装(英制:0.08英寸×0.05英寸,公制:2.0mm×1.2mm),具有以下核心优势:

  1. 体积小巧:适配智能遥控器、蓝牙耳机、安防摄像头、智能家居传感器等小型化设备的紧凑布局;
  2. 自动化兼容:兼容SMT自动化贴装生产线,生产效率高,降低人工成本与装配误差;
  3. 可靠性稳定:封装结构抗振动、抗冲击性能良好,适合批量应用场景(如家电量产)。

四、典型应用场景

结合参数特点,该器件的核心应用场景包括:

  1. 红外遥控设备:电视、空调、机顶盒遥控器的发射端,940nm波长与主流红外接收管兼容,宽视角满足日常使用无需精准对准;
  2. 近距离感应系统:智能门锁人体感应、自动门接近检测、智能家居红外接近开关;
  3. 安防监控辅助:部分低照度摄像头的红外补光辅助(需匹配功率,避免过亮干扰);
  4. 小型电子通信:智能手环、蓝牙耳机的近距离红外数据传输模块。

五、使用注意事项

为确保性能与可靠性,需注意以下要点:

  1. 电流控制:正向电流(If)不得超过30mA,建议驱动电路串联100~200Ω限流电阻(适配3.3V电源);
  2. 反向防护:反向电压不超过5V,需并联反向保护二极管(如1N4148);
  3. 功耗散热:避免密集贴装导致局部过热,工作时需保证器件周围通风;
  4. 温度范围:超出-40℃~+85℃可能导致性能下降,户外应用需增加温度防护设计。

该器件以高性价比、稳定性能与小型化设计,成为红外应用领域的主流选择,适配多场景的低成本解决方案需求。

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
