FNR6028S8R2MT 产品概述

一、产品简介

FNR6028S8R2MT 是长江微电(cjiang)推出的一款磁胶屏蔽功率电感,规格为 8.2µH ±20%,额定电流 2.5A,饱和电流(Isat)2.5A,直流电阻(DCR)约 72mΩ,SMD 封装,外形尺寸 6×6mm。该型号面向中小功率电源电路,兼顾体积、温升及磁屏蔽性能,适用于空间受限且要求较高电流能力的应用场景。

二、主要电气参数

  • 电感值:8.2 µH,公差 ±20%
  • 额定电流:2.5 A(连续载流能力)
  • 饱和电流(Isat):2.5 A(在该电流下电感值明显下降)
  • 直流电阻(DCR):约 72 mΩ(低 DCR 有助于降低功耗)
  • 类型:磁胶屏蔽电感(屏蔽式结构可减少对周边器件的电磁干扰)
  • 封装:SMD,外形尺寸 6×6 mm

三、产品特性与优势

  • 小型化尺寸(6×6mm),便于高密度 PCB 布局;
  • 屏蔽磁芯设计,降低外部磁场泄漏,改善 EMC 表现;
  • 相对较低的 DCR,有利于减小导通损耗和提高效率;
  • 饱和电流与额定电流匹配,适合要求稳定电感值的功率路径;
  • SMD 封装适配自动化贴装和回流焊工艺,提高生产效率。

四、典型应用场景

  • DC-DC 降压(buck)转换器输出电感;
  • 电源管理模块(PMIC)、不间断电源 UPS 的开关电源部分;
  • 通信设备、工业控制与仪器等对电源滤波与稳压有要求的系统;
  • 嵌入式设备与便携电子需兼顾体积与散热的电源方案。

五、选型与使用建议

  • 建议在实际运行中对电感进行电流余量考量,通常最好将工作电流低于额定电流以减少温升与靠近饱和区的风险;
  • 注意饱和特性:当电流接近 Isat 时,电感值会下降,可能影响环路稳定,务必在仿真或样机测试中验证;
  • DCR 与功耗:72 mΩ 在 2.5A 条件下会产生一定的 I²R 损耗(约 0.45 W),需评估散热条件与周边温升;
  • 焊接与回流:采用规范的回流曲线进行贴片焊接,避免过长高温暴露影响黏结与性能;
  • PCB 布局:将电感、开关器件和输入/输出电容按电源拓扑最短回路布置,减少寄生环路和 EMI。

六、封装与可靠性

FNR6028S8R2MT 为 SMD 封装,适用于托盘或卷带(Tape & Reel)自动化贴装。磁胶屏蔽结构在实际可靠性测试中表现良好,常规测试包括温度循环、湿热与焊接热冲击。推荐在产品设计阶段进行热仿真与实际运行温升测试,以确认长时间工作的可靠性。

七、总结

FNR6028S8R2MT 是一款定位于中小功率、空间受限场合的 8.2µH 屏蔽功率电感,凭借 6×6mm 的小尺寸、2.5A 的电流承载能力及较低 DCR,适合用作降压转换器输出电感或一般电源滤波元件。在选型时建议关注工作电流的余量、饱和特性与热耗散,并通过样机验证其在目标应用中的环路稳定性与 EMC 表现。若需进一步的规格书、S-参数或样品验证建议联系厂商获取完整数据手册。

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
