FNR4020S5R6MT — 5.6µH 磁胶屏蔽功率电感(长江微电 cjiang)

一、产品简介

FNR4020S5R6MT 是长江微电(cjiang)推出的一款表面贴装磁胶屏蔽功率电感,额定电感值 5.6µH(±20%),专为中小功率点位负载和开关电源电路设计。封装为 SMD,外形尺寸约 4×4 mm,结构屏蔽、磁漏小,适合对 EMI 要求较高的应用场合。

二、关键电气参数

  • 电感值:5.6µH ±20%
  • 额定电流(Idc):1.8A(推荐最大连续电流)
  • 饱和电流(Isat):2.4A(磁芯开始显著降感时的参考值)
  • 直流电阻(DCR):约 117 mΩ(影响效率与发热)
    这些参数决定了器件在不同偏置与频率下的工作特性,±20% 容差在功率滤波与能量传输中属于常见范围。

三、典型应用场景

  • DC-DC 降压/升压转换器的电感元件(点位电源)
  • 嵌入式系统、通信设备、便携式电源管理模块
  • USB 电源、LED 驱动、车载电子低功耗电路
  • EMI 抑制与电源滤波网络

四、设计与布局建议

  • 将电感靠近开关管或开关节点布局,尽量缩短高 di/dt 回路长度以降低寄生噪声。
  • 输入侧与输出侧电容尽量靠近电感与开关器件,减小环路面积。
  • 对于较高电流或长期满载场景,建议留有一定电流余量,尽量不要使连续电流接近 Isat,以免感值骤降影响稳定性。
  • DCR 为 117 mΩ,会带来一定损耗与发热,需在系统热设计中考虑器件周围散热条件。

五、可靠性与封装

  • 屏蔽结构有利于降低磁辐射,对邻近敏感信号影响小。
  • SMD 封装适用于自动贴装与回流焊工艺,建议按通用 JEDEC 回流曲线组装,避免超过元件厂家规定的温度极限(具体焊接曲线请参照供应商资料)。

六、选型与使用注意

  • 若工作电流长期接近或超过 1.8A,应考虑更大额定电流或更低 DCR 的型号。
  • 在高频或高温工况下,实际电感值会随偏置与温度变化,设计时应预留裕量。
  • 订购型号:FNR4020S5R6MT,品牌:cjiang(长江微电),封装:SMD,规格页与可靠性测试报告请向供应商索取以便最终验证。

如需与具体电源拓扑(如同步降压、非隔离升压等)匹配建议或 PCB 布局示意,可提供电路参数以便给出更精确的选型与实装指导。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
