FNR6028S470MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,封装为 SMD 贴片,外形尺寸约 6×6 mm。标称电感值为 47 μH,允差 ±20%;额定电流 1.1 A,饱和电流(Isat)为 1.3 A;直流电阻(DCR)约 410 mΩ。该器件以磁胶屏蔽结构为特色,兼顾较高电感量与良好抗干扰性能,适用于体积受限的电源滤波与能量传输场合。
磁胶屏蔽结构使器件具有较好的磁通限制与外部干扰抑制能力,相比无屏蔽电感在系统 EMI 控制上更有优势。6×6 mm 的紧凑尺寸适合中小功率点到点电源、降压转换器与滤波网络。高电感值配合中等额定电流使其在需要较大储能且电流不太高的场景表现良好。
总结:FNR6028S470MT 以 47 μH、1.1 A 的额定电流和 6×6 mm 的 SMD 封装,适合对体积与 EMI 有一定要求的中小功率电源应用。在实际设计中需综合考虑 DCR 导致的损耗、工作电流裕量以及温升与频率特性,按厂商推荐的焊接与测试流程进行验证,以确保系统长期可靠运行。

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.
