FNR5040S560MT 功率电感产品概述

FNR5040S560MT是长江微电(cjiang)推出的一款磁胶屏蔽贴片功率电感,针对小型化、低电磁干扰(EMI)需求的电子设备设计,凭借紧凑的5×5mm封装和均衡的电气性能,成为消费电子、物联网、小型电源等领域的常用器件。

一、产品核心定位

该电感聚焦中低功率高密度电路场景,兼顾电磁兼容性与功率密度,适配贴片自动化组装线,是替代传统插件电感的主流选择之一。其核心定位可概括为:

  • 小体积:满足10mm以下厚度设备的集成需求;
  • 低EMI:磁胶屏蔽结构降低对周边敏感电路的干扰;
  • 高性价比:平衡电感值、电流能力与直流电阻,适配消费级到工业级基础应用。

二、关键电气参数深度解析

1. 电感值与精度

56uH ±20%,覆盖多数DC-DC转换、滤波电路的储能/滤波需求。±20%的精度无需额外校准,可满足消费电子、物联网设备的批量生产一致性要求。

2. 电流能力

  • 额定电流(900mA):连续工作时的最大电流,此时电感温升符合行业规范(通常≤40℃),保证长期稳定运行;
  • 饱和电流(1.2A):磁芯未完全饱和的最大瞬时电流,超此值电感值会骤降(可能降至额定值的50%以下),需避免持续过载。

3. 直流电阻(DCR)

494mΩ,在5×5mm封装下实现了较低的损耗,可减少功率电路的发热与效率损失(例如,900mA电流下的损耗约为0.4W)。

4. 屏蔽特性

磁胶屏蔽结构相比非屏蔽电感,可降低约30%的电磁辐射,避免对射频模块、传感器等敏感电路的干扰,符合现代电子设备的EMC要求。

三、封装与工艺优势

1. 封装规格

SMD 5×5×4mm(典型高度),体积仅为传统插件电感的1/3,可集成于手机、智能手表等超薄设备的主板中。

2. 工艺特点

采用磁胶一体化成型:

  • 磁芯采用高导磁率材料,保证电感值稳定性;
  • 胶层抑制磁芯振动噪声,同时简化组装流程;
  • 焊盘符合IPC标准,支持回流焊、波峰焊,适配无铅制程。

四、典型应用场景

1. 消费电子终端

  • 手机、平板的电源管理单元(PMU):为CPU、射频模块提供稳定直流供电;
  • 智能手表、蓝牙耳机:适配低功耗电路的储能需求。

2. 小型电源模块

  • LED驱动电源(台灯、背光):56uH电感满足12V/500mA以内的驱动需求;
  • USB-C充电器(5V/2A):平衡体积与效率,符合便携设备的快充要求。

3. 物联网设备

  • 传感器节点(温湿度、运动传感器):低电流损耗适配电池供电场景;
  • 智能门锁、智能音箱:抑制电路噪声,避免干扰WiFi/Bluetooth信号。

4. 通信模块

  • WiFi6、蓝牙5.0模块:作为滤波电感,减少射频信号干扰。

五、品牌与可靠性保障

长江微电作为国内电感领域的成熟厂商,FNR5040S560MT经过严格可靠性测试:

  • 环境测试:-40℃~+85℃温度循环(1000次)、85℃/85%RH湿度测试(500h);
  • 机械测试:10~2000Hz振动测试(加速度2g)、1.5m跌落测试(水泥地);
  • 环保认证:符合RoHS、REACH标准,不含铅、镉等有害物质。

总结

FNR5040S560MT凭借小体积、低EMI、均衡的电流与电感性能,成为中低功率电路的高性价比选择,适配多种小型化电子设备的设计需求,适合批量应用于消费电子、物联网等领域。

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
