FNR5040S562MT 磁胶屏蔽功率电感产品概述

一、产品定位与核心优势

FNR5040S562MT是长江微电(cjiang)推出的小型化SMD功率电感,针对低电流、高电感需求的场景设计,核心优势聚焦于「小体积适配+低干扰+稳定性能」:

  1. 磁胶屏蔽结构:抑制电磁辐射,适配对EMI敏感的电路(如模拟信号、射频模块);
  2. 紧凑封装:5×5mm SMD尺寸,兼容便携式设备的小型化PCB设计;
  3. 高电感值集成:在小封装下实现5.6mH高电感,满足滤波、储能的基础需求;
  4. 参数稳定性:±20%精度覆盖商用级场景,磁胶固定磁芯减少振动导致的漂移。

二、关键电气参数深度解析

1. 电感值与精度

标注为「562」(即56×10²μH=5.6mH),精度±20%——属于商用级常规范围,无需额外校准即可满足大多数消费电子、物联网终端的滤波需求;高电感值在小体积下实现,依赖长江微电的绕组绕制工艺优化。

2. 电流特性(核心使用限制)

  • 额定电流(Idc=92mA):正常工作时电感温升不超过允许值(常规≤40℃)的最大电流,需作为实际应用的电流上限参考(超过则加速电感老化);
  • 饱和电流(Isat=120mA):磁芯饱和时的电流——此时电感值会下降约30%(磁芯磁导率骤降),滤波/储能效果失效,需避免工作电流接近此值(建议留20%余量)。

3. 直流电阻(DCR=50.7Ω)

绕组的直流电阻直接影响I²R损耗,该值在「5.6mH高电感+5×5mm小封装」下属于合理范围:磁胶屏蔽结构优化了绕组排布,减少了额外损耗,适合低电流场景的能效控制。

4. 屏蔽特性

磁胶屏蔽采用环氧树脂包裹磁芯,相比非屏蔽电感:

  • 电磁辐射降低60%以上,减少对周边敏感电路的干扰;
  • 磁芯机械稳定性提升,抗振动/冲击能力增强。

三、封装与物理特性

  • 封装类型:SMD(表面贴装),尺寸5×5mm(长×宽),适配自动化回流焊工艺,兼容0402/0603等常规贴片元件的PCB布局;
  • 结构细节:磁胶包裹磁芯+漆包线绕组,引脚为标准SMD扁平脚,焊接可靠性高(符合IPC-A-610标准);
  • 环保特性:符合RoHS无铅标准,可用于出口类电子设备。

四、典型应用场景

基于「低电流+高电感+小体积」的特性,该电感适用于以下场景:

  1. 便携式消费电子:蓝牙音箱、无线耳机的电源滤波电路(过滤低频噪声);
  2. 物联网低功耗终端:传感器节点、智能手环的信号滤波与3.3V电源稳压;
  3. 小型DC-DC模块:12V转5V/3.3V的低功率电源输出滤波(电流≤90mA);
  4. 工业辅助电路:PLC的低电流信号处理、小型继电器驱动的滤波环节。

五、品牌与可靠性保障

长江微电作为国内电感制造头部企业,该产品经过全流程可靠性测试:

  • 回流焊温度循环(260℃×3次)、高低温存储(-40℃85℃)、振动测试(102000Hz);
  • 长期工作参数漂移≤5%(1000小时老化测试),适用于7×24小时稳定运行的场景。

该电感以「高性价比+小体积适配」为核心竞争力,覆盖消费电子、物联网等多个低电流功率电感需求场景,是小型化设备的优选方案。

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
