FNR4020S101MT 是长江微电(cjiang)推出的一款 SMD 功率电感,封装尺寸约 4.0 × 4.0 mm(4020 封装),标称电感量 100 µH,公差 ±20%。属于磁胶屏蔽结构的功率电感,面向对体积有限但需较大电感量的电源和滤波场合设计。额定直流电流(Ir)为 430 mA,饱和电流(Isat)为 530 mA,直流电阻(DCR)为 2.02 Ω。
总体而言,FNR4020S101MT 以小封装提供较大电感量,适合对电感量要求高但电流与效率要求适中或偏低的滤波场合;在设计时需关注其较高的 DCR 与饱和电流限制,做好热管理与电流留余。

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.
