IR333C-A R档为台湾亿光(EVERLIGHT)5mm穿透式红外发射二极管(LED),标称主波长940nm,属于不可见红外波段发射器件。该器件以高辐射强度、紧凑封装及良好的电热特性适配于遥控、光电检测、近距离通信及存在/障碍检测等应用。注意本器件为发射端(红外LED),并非接收头。
在常用驱动电流20 mA条件下,辐射强度可达约7.8 mW/sr,适合与常见940 nm接收器(硅或硅基光电二极管/接收模块)配合使用。发射角度与辐射分布受透镜形状影响,典型5mm圆头封装为中等到较宽发散角,便于近距均匀照射。若需远距或窄束照射,应配合透镜或采用聚光封装。
标准5mm插件封装(直径5mm,总长约8.6mm),便于手工装配和波峰/回流焊后插装固定。引脚间距与穿孔尺寸符合通用DIP安装规范,便于在板上固定与焊接。
器件适应工业级工作温度(-25 ℃ 至 +85 ℃)。在高温环境或高平均功率应用下,应关注结温管理与热散逸,必要时降低驱动电流或增加散热/降低占空比。出厂通常为防潮防静电包装,建议在干燥箱或防潮条件下储存与运输。
结论:IR333C-A R档为一款性能稳定、封装通用的940 nm红外发射LED,适合多种近距红外发射应用。选型时应综合考虑驱动方式、热管理和接收端匹配以获得最佳系统性能与长期可靠性。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
