FNR6045S3R0NT 功率电感产品概述

FNR6045S3R0NT是长江微电(cjiang)推出的一款磁胶屏蔽型表面贴装(SMD)功率电感,专为中低功率直流转换场景设计,核心围绕“小体积、高电流、低损耗、低EMI”四大需求优化,是消费电子、电源模块等领域的实用型电感解决方案。

一、产品定位与核心优势

该电感定位为中低功率DC-DC转换专用电感,区别于普通电感的核心优势体现在:

  1. 磁胶屏蔽抗干扰:采用磁胶包裹磁芯结构,大幅降低漏磁,减少对周边电路的电磁干扰(EMI),适配对EMI敏感的电子设备;
  2. 高饱和电流过载能力:饱和电流达6.2A,比额定电流(4.2A)高出47%,可应对电路瞬间过载场景,提升系统可靠性;
  3. 低DCR降低损耗:直流电阻仅26mΩ,铜损(I²R损耗)显著降低,减少发热、提升电源转换效率;
  4. 小封装适配小型化:6×6mm SMD封装,厚度约4.5mm(型号“6045”隐含尺寸信息),满足消费电子轻薄化、设备高密度集成需求。

二、关键电气参数详细解析

1. 电感特性

电感值为3μH±30%,符合功率电感常用规格范围;磁胶屏蔽结构使电感值受温度、振动影响小,稳定性优于非屏蔽电感,适合宽温环境(典型工作温度-40℃~125℃)。

2. 电流能力

  • 额定电流(Irms)4.2A:指电感在25℃环境下,DCR升温不超过规格值(通常20~40℃)的连续工作电流,是长期可靠工作的参考值;
  • 饱和电流(Isat)6.2A:指电感值下降30%时的电流,代表瞬间过载能力,可避免电路电流突变时电感失效。

3. 直流电阻(DCR)

26mΩ的低电阻值,意味着相同电流下发热更少——例如4.2A电流时,损耗功率仅为I²R=4.2²×0.026≈0.46W,远低于同规格普通电感(通常DCR≥30mΩ)。

三、物理封装与结构设计

1. 封装与尺寸

采用SMD表面贴装封装,外形尺寸为6mm×6mm×4.5mm(长×宽×高),符合IPC标准,可通过自动化贴片机(回流焊)批量生产,适配高密度PCB布局。

2. 结构特点

  • 磁胶屏蔽磁芯:替代传统金属屏蔽罩,既减少漏磁,又降低电感整体重量与体积;
  • 漆包线绕制:采用高纯度漆包铜线,确保低DCR与良好的电流承载能力;
  • 抗振动设计:磁芯与线圈固定牢固,可承受2G~5G振动(符合消费电子、车载低功率场景要求)。

四、品牌与可靠性保障

长江微电(cjiang)是国内电感行业知名厂商,FNR6045S3R0NT通过以下保障提升可靠性:

  1. 环保认证:符合RoHS 2.0、REACH等环保标准,无有害物质;
  2. 可靠性测试:经过高低温循环、湿热老化、振动冲击等测试,确保1000小时以上寿命(典型应用场景);
  3. 一致性管控:电感参数一致性好,批量生产时性能波动小,适合大规模应用。

五、典型应用场景

FNR6045S3R0NT广泛适配中低功率电源电路,典型场景包括:

  1. 消费电子:手机、平板、笔记本电脑的CPU/内存供电DC-DC模块;
  2. LED驱动电源:小功率LED灯串、背光驱动的降压电路;
  3. 物联网设备:智能穿戴(手表、手环)、智能家居(传感器节点)的供电模块;
  4. 小型电源模块:车载USB充电器、便携式充电宝的升压/降压电路;
  5. 通信设备:小型路由器、WiFi模块的电源滤波电路。

总结

FNR6045S3R0NT凭借磁胶屏蔽、高饱和电流、低DCR、小封装等核心特性,成为中低功率电源场景的高性价比电感选择。其可靠性与适配性,可满足消费电子、物联网、小型电源等多领域的设计需求。

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
