LTV-814S-TA1-B 是来自 LITEON(台湾光宝)的一款单通道贴片光电隔离器(SMD-4P / SOP-4 封装)。该器件将红外发光二极管与硅光电晶体管封装在一起,提供电气隔离与信号传输功能。器件支持交流/直流输入驱动,隔离耐压高达 5kVrms,适合低速信号隔离、逻辑接口和一般工业控制场合。
总结:LTV-814S-TA1-B 是一款适用于通用低速信号隔离、具有高隔离电压与低 VCE(sat) 特性的单通道贴片光耦。选择时应结合 CTR 波动、驱动电流、速度与功耗限制进行系统级考虑,以确保稳定可靠的隔离传输。若需更高输出电流、更快速度或更稳定的 CTR,请根据应用进一步比较同类光耦或使用带隔离驱动器件。

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.
