WPN4020H3R3MT 为顺络(Sunlord)推出的一款表面贴装功率电感,封装尺寸为 4020(4.0×4.0 mm),标称电感值 3.3 μH(标称代码 3R3),公差 ±20%。该器件面向开关电源、点式电源滤波和电源变换器的能量存储与纹波抑制应用,兼顾体积、导流能力与热性能。
选择时重点关注电感在大直流偏置下的有效电感值、DCR 对系统效率的影响以及封装是否满足 PCB 布局空间。若需要更高电流能力或更低 DCR,可优先考虑相近尺寸下更低 DCR 或更大截面的产品;若空间更受限,可查找小尺寸但在电流与损耗之间做权衡的型号。
作为商业级功率电感,WPN4020H3R3MT 适配主流电子制造工艺,可满足一般工业产品对温度循环、湿热及振动的可靠性要求。实际产品验证请参考顺络提供的详细数据手册与可靠性测试报告。
总结:WPN4020H3R3MT 在 4×4 mm 紧凑封装中提供 3.3 μH 的能量存储、3.45 A 的持续电流能力及较低的 DCR,适合中等功率开关电源与点式电源应用。在设计时应注意直流偏置、散热与焊接工艺以确保长期稳定工作。若需更详细的电气曲线、温升数据及封装图纸,请参考顺络官方数据手册或联系供应商获取样片验证。

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.
