顺络WPN4012H3R3MT属于小体积SMD功率电感,专为中低功率电源管理场景设计,核心满足消费电子、IoT设备、车载辅助电路等领域的紧凑化需求。其4×4mm封装占板面积仅16mm²,适配高密度PCB布局,典型应用包括:
该产品的关键参数围绕“功率电感的储能效率、电流承载能力”展开,具体意义如下:
电感值为3.3μH ±20%,属于功率电感常规精度范围(相比精密电感的±5%更适配电源场景)。3.3μH的储能容量可满足1-2.1A电流下的DC-DC转换需求,避免电感值过大导致响应速度慢、体积冗余,过小则储能不足。
DCR是绕组铜损的核心来源,104mΩ的低阻值在同体积同电流电感中表现优异:
采用SMD 4×4×1.2mm表面贴装封装(行业标注通常省略高度,但顺络WPN系列默认高度1.2mm),符合IPC-J-STD-020无铅焊接标准,适配回流焊、波峰焊工艺,生产兼容性强。
该产品满足工业级宽温要求(-40℃~+125℃),在极端温度下性能稳定:
综上,顺络WPN4012H3R3MT凭借“小体积、低DCR、高饱和电流”的优势,成为中低功率电源设计的高性价比选择,尤其适配对空间敏感的便携设备与IoT场景。

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.
