FNR3015SR50NT 为长江微电(cjiang)推出的一款磁胶屏蔽功率电感,封装为 SMD,外形尺寸 3×3 mm。标称电感量 500 nH,公差 ±30%,额定电流 2.8 A,饱和电流(Isat)4.2 A,直流电阻(DCR)约 39 mΩ。该器件针对开关电源、点到点供电和电源滤波等场景,提供小体积、高电流通过能力与屏蔽特性相结合的解决方案。
基于 DCR 可估算导通损耗:
选择长江微电(cjiang)品牌时,应关注批次一致性与出厂测试报告(DCR、Isat、外观检验)。在样机阶段建议进行电感值、DCR、温升及寿命加速试验以确认在目标工况下的稳定性。
型号:FNR3015SR50NT;品牌:cjiang(长江微电);封装:SMD 3×3 mm。采购时请向供应商确认最小起订量、出厂测试数据(如 DCR 与 Isat 测试条件)及可提供的封装卷带信息,以便快速投入生产。
如需将本器件用于特定电源拓扑(例如同步降压、多相或高频开关),可提供电路条件,我可协助进行更细致的选型与布局建议。

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.
