FNR5020S4R7MT 是长江微电(cjiang)推出的一款表面贴装磁胶屏蔽功率电感,封装尺寸为 5×5mm,电感量 4.7 μH(精度 ±20%),适用于中等功率的开关电源与电流滤波场合。器件采用磁胶屏蔽结构,磁通泄漏小、抗干扰能力强,便于在空间受限且要求EMC性能较高的系统中应用。
选择时关注电感值与误差范围、额定电流与饱和电流、DCR 对效率的影响以及尺寸限制。若需要更高电流能力或更低 DCR,可考虑同尺寸或更大尺寸的功率电感替代;如对精度要求更高,可选择 ±10% 或 ±5% 的型号。
如需样品、详细封装图或更具体的电气特性曲线(如频率响应、温升曲线、磁饱和特性),建议联系供应商或查阅产品数据手册以获得完整参数与推荐封装尺寸。

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.
