K7803M-1000R3 是 YLPTEC(易川) 推出的降压型开关稳压模块,输入电压范围宽(6V~36V),输出固定 3.3V,额定输出电流 1A。模块采用高频开关设计,典型转换效率可达 90%,静态电流仅 300µA,体积小(SIP 封装,11.6×7.5×10.2mm),无需外加散热片即可在工业环境中可靠工作。
模块内置短路保护与自动故障恢复功能,能在过流或短路后自动限制输出并在故障解除后恢复工作,提升系统可靠性。宽温设计与低静态电流使其适合长期连续运行的工业应用场景。
该系列模块是三端线性稳压器的高效替代品,特别适用于工控系统、电力监控、电源模块、仪器仪表、嵌入式设备等需要从较高总线电压降至 3.3V 的场合。由于效率高、发热低,可用于空间受限且散热条件有限的设备中。
封装形式:SIP,尺寸 11.6×7.5×10.2mm,便于板上直接插装或空间受限的模块化设计。
K7803M-1000R3 以其高效、低损耗、稳健的保护特性,成为替代传统线性稳压器的理想选择,特别适合工业与仪表类电源设计需求。品牌:YLPTEC(易川)。

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.
