FNR4018S6R8MT 产品概述

一、概述

FNR4018S6R8MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,标称电感值为 6.8µH,精度 ±20%,为表面贴装封装(SMD),外形尺寸约 4×4mm。该器件针对中小功率开关电源与电源滤波场景设计,兼顾高饱和电流与低直流损耗,适合空间受限且要求可靠性的功率电路使用。

二、主要参数

  • 电感值:6.8µH ±20%
  • 额定电流(Ir):1.5A(连续工作限值,推荐工作点)
  • 饱和电流(Isat):2.0A(电感下降到初始值一定比例时测得)
  • 直流电阻(DCR):0.143Ω(143mΩ)
  • 类型:磁胶屏蔽电感(磁屏蔽,低漏磁)
  • 封装形式:SMD,外形约 4×4mm
  • 品牌:cjiang(长江微电)
  • 型号:FNR4018S6R8MT

三、产品特点

  • 小型化设计:约 4×4mm SMD 封装,利于高密度贴装与体积受限的模块化设计。
  • 良好电流处理能力:1.5A 额定电流配合 2.0A 饱和电流,适合小功率升降压转换器和电源滤波场景。
  • 低直流电阻:143mΩ 降低导通损耗,有利于提升效率并减小发热。
  • 磁胶屏蔽结构:抑制磁通外泄、降低对周边元件的干扰,提升 EMI 性能与系统稳定性。
  • 工艺兼容:适合标准 SMT 回流焊工艺,便于自动化贴装与大批量生产。

四、典型应用

  • 开关电源(DC-DC)输入/输出滤波与能量储存
  • 移动设备与便携式电源管理模块
  • LED 驱动与背光电源
  • 工业与通信设备中的滤波/储能回路
    (建议在具体应用中根据温升、纹波电流与频率特性进行仿真与验证)

五、使用建议与注意事项

  • 电流裕量:为保证长期可靠性与避免磁芯饱和,建议工作电流在额定电流以下并考虑温升余量。
  • 温度与散热:高电流工作时会产生热量,设计时应预留热通道并避免长期接近最大额定电流。
  • 焊接工艺:兼容无铅回流焊,但请遵循器件制造商或 PCB 工艺的回流曲线,避免过高峰值温度或反复回流。
  • PCB 布局:建议将电感尽量靠近功率器件与电源引脚,缩短高频回路走线,配合适当的去耦电容以降低 EMI。
  • 测试与验证:实际电感值与 DCR 受温度、工艺差异影响,建议在最终应用板上进行温升与频率响应测试。

六、封装与订购信息

  • 型号:FNR4018S6R8MT
  • 品牌:cjiang(长江微电)
  • 封装:SMD,4×4mm 级别(具体机械图及推荐焊盘请参照厂商数据手册)
  • 包装:适配 SMT 生产的卷带包装或按客户要求定制(具体请与供应商确认)

本概述基于典型规格信息整理,具体电气与机械参数、测试条件、可靠性认证及可用库存请以长江微电官方数据手册与销售提供的最新资料为准。

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
