FNR4020S6R8MT 为长江微电(cjiang)出品的一款功率屏蔽贴片电感,主要参数如下:标称电感值 6.8 µH(公差 ±20%);额定直流电流 Irated = 1.6 A;饱和电流 Isat = 2.4 A;直流电阻 DCR = 163 mΩ;封装形式 SMD,外形尺寸约 4.0 × 4.0 mm。器件类型为磁胶屏蔽电感,适用于开关电源及点对点电源滤波等对体积与电流能力有要求的场合。
该款采用磁胶屏蔽结构,能有效抑制磁通外泄,降低对周边敏感电路的干扰,适合高密度贴片化布局。4×4 mm 的SMD封装兼顾空间利用与电流承载能力,支持常规回流焊工艺,便于自动化贴装与大规模生产。
总结:FNR4020S6R8MT(6.8 µH,1.6 A,Isat 2.4 A,DCR 163 mΩ,4×4 mm)是面向中等电流、空间受限电源应用的屏蔽功率电感,具有体积小、屏蔽性能好、适配SMT工艺等优点。用户在设计时需关注直流偏置下的电感衰减、器件功耗与散热布板,以保证长期可靠运行。

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.
