PT91-21B/TR7 是由台湾亿光(Everlight Electronics Co Ltd)制造的红外接收管,采用表面贴装型(SMD)封装设计。其主要工作波长为940nm,非常适合用于红外信号的接收与处理。这款红外接收管具有优良的性能和可靠性,适用于多种电子应用,尤其是在消费电子、通信、工业控制和安防系统等领域。
PT91-21B/TR7 的主要参数如下:
PT91-21B/TR7 的工作原理基于光电效应,其内部结构能够有效地接收波长为940nm的红外信号。当外部红外光照射到接收管的光敏区域时,光子会激发内部的电子,从而产生电流变动。接收管对红外信号的敏感度使其能在不同的光照环境下进行稳定工作,并确保信号完整性,从而为后续电路的处理提供可靠的数据支持。
得益于其高性能特性,PT91-21B/TR7 被广泛应用于以下领域:
综上所述, PT91-21B/TR7 不仅具备优越的电性能,还在多种应用场合中具有广泛的兼容性和适应性。其在红外信号接收方面的卓越表现,使其成为现代电子设备不可或缺的元件之一。随着市场对红外技术需求的持续增长,PT91-21B/TR7将继续在各个领域发挥重要作用。

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.
