FNR6028S1R0MT 功率电感产品概述

FNR6028S1R0MT是长江微电(cjiang)推出的一款磁胶屏蔽贴片功率电感,专为中等功率密度的电子设备设计,兼具低损耗、低电磁干扰(EMI)和高可靠性等特点,广泛适配DC-DC转换、电源模块等场景,是小型化设备的高性价比电感选型。

一、核心电气参数详解

该电感的核心参数明确了性能边界,是选型的关键依据:

  1. 电感值与精度:标称电感值为1μH,精度±20%,满足大多数电源电路对电感量的常规要求,同时留有公差适应生产一致性;
  2. 电流额定值:额定电流(Irms)5.7A——指电感持续工作时,线圈温度上升不超过40℃(行业常规阈值)的最大电流,是设备正常运行的安全阈值;饱和电流(Isat)7A——指电感值下降30%时的临界电流,此参数比额定电流高1.3A,为过载保护提供充足裕量,避免电路因电感饱和导致输出电压波动;
  3. 直流电阻(DCR)13mΩ:较低的DCR意味着线圈损耗小,可有效降低电感热耗散,提升电源转换效率(额定电流下损耗仅约0.42W)。

二、封装与物理特性

FNR6028S1R0MT采用SMD贴片封装,尺寸为6×6mm(行业标识“6028”对应6mm×6mm×2.8mm高度),体积小巧,适配对空间要求严格的小型化设备; 其采用磁胶屏蔽结构:相比非屏蔽电感,磁胶包裹磁芯可显著抑制漏磁,降低电磁辐射,减少对周边敏感电路的干扰,尤其适合通信、车载等对电磁兼容性(EMC)要求较高的场景。

三、典型应用场景

基于参数特性,该电感主要应用于以下领域:

  1. DC-DC转换器:作为降压/升压电路的储能元件,适配笔记本电脑、平板等便携设备的核心供电模块;
  2. 电源模块:用于工业控制、通信基站的低/中功率电源单元,满足5A左右的电流需求;
  3. 消费电子:小型家电(如智能音箱、路由器)的电源电路,利用低EMI特性避免信号干扰;
  4. 车载电子:辅助供电系统(如车载显示屏、传感器模块),适应宽温环境的可靠性需求。

四、性能优势与可靠性

  1. 低损耗高效能:13mΩ的DCR配合优化的磁芯材料,使电感在额定电流下热耗散小,无需额外散热设计即可稳定工作;
  2. 抗干扰能力强:磁胶屏蔽结构通过抑制漏磁,有效降低EMI,减少电路设计中的滤波成本;
  3. 过载裕量充足:饱和电流7A远高于额定电流,短暂过载时仍能保持电感值稳定,避免输出异常;
  4. 品牌可靠性:长江微电作为国内功率电感主流厂商,产品经过高低温循环、振动冲击等严格测试,可满足工业级应用的环境要求(常规-40℃~+125℃)。

五、选型与使用注意事项

  1. 电流匹配:实际工作电流需低于额定电流5.7A,避免长时间过流导致线圈老化;
  2. 温度范围:需确认应用场景的工作温度是否在产品允许范围内(建议咨询厂商具体参数);
  3. 焊接工艺:贴片安装时遵循SMD回流焊规范,避免温度过高损坏磁芯;
  4. 布局设计:虽为屏蔽电感,仍建议与敏感电路(如模拟信号电路)保持适当距离,进一步优化EMC性能。

总结:FNR6028S1R0MT凭借平衡的电气参数、小型化封装和低EMI特性,成为中等功率电子设备的可靠选型,覆盖从消费电子到工业控制的多场景需求。

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
