FRICM-5020-142 共模滤波器产品概述

FRICM-5020-142是长江微电(cjiang)推出的SMD贴片式双通道共模滤波器,针对电子系统电磁干扰(EMI)抑制需求设计,兼顾信号完整性与电流承载能力,适配多场景低压小功率电路滤波。

一、产品定位与核心功能

共模滤波器是EMI抑制的核心器件,核心作用是衰减共模噪声(两路线路上相位/方向相同的干扰),同时保留有用差模信号(相位/方向相反的传输信号)。FRICM-5020-142定位于中小功率、高密度安装场景,通过优化磁芯与绕组设计,在100MHz关键EMI频段实现高效噪声抑制,满足低损耗、宽温工作需求。

二、关键性能参数深度解析

参数直接决定适用场景,以下解析核心参数的实际意义:

1. 共模抑制性能:1.4kΩ@100MHz

100MHz是电子设备常见干扰频段(高速接口、无线二次谐波等),该参数表明产品对该频段共模噪声的衰减能力强——共模阻抗越高,干扰抑制越显著,且不影响有用信号传输(差模阻抗远低于共模阻抗)。

2. 电流承载与损耗:1.5A额定电流,36mΩ直流电阻(DCR)

  • 1.5A额定电流:覆盖USB供电、DC-DC输出、传感器模块等中小功率电路需求;
  • 36mΩ低DCR:电流损耗低(P=I²R),发热少,无需额外散热,可长期稳定工作。

3. 电压与绝缘特性:50V额定电压,10MΩ绝缘电阻

  • 50V额定电压:适配5V/12V/24V等常规低压电路,满足安全规范;
  • 10MΩ绝缘电阻:引脚间绝缘良好,防止共模噪声耦合,提升抗干扰可靠性。

4. 宽温工作范围:-40℃~+125℃

符合汽车电子、工业控制等严苛环境要求(车载低温启动、工业高温工况),极端温度下性能无漂移。

三、封装与可靠性设计

FRICM-5020-142采用SMD-4P 5x5mm贴片封装,设计优势明显:

1. 紧凑封装,高密度安装

5x5mm尺寸节省PCB空间,适配手机、笔记本等高密度布线场景;4引脚双通道结构,可同时滤波两路信号/电源,无需额外器件。

2. 可靠性设计

  • 长江微电成熟磁芯/绕组工艺,宽温下磁性能稳定;
  • 引脚与封装结合强度高,承受贴片/回流焊应力;
  • 符合RoHS环保要求,适配全球市场规范。

四、典型应用领域

产品参数特性使其适用于多场景:

1. 消费电子

  • 手机/平板/笔记本高速接口滤波(USB Type-C、HDMI),抑制接口噪声;
  • 智能音箱、路由器电源滤波,减少电磁辐射。

2. 工业控制

  • PLC、传感器模块信号滤波,防止电机/变频器噪声干扰;
  • 小型工业电源输出滤波,提升电源稳定性。

3. 汽车电子

  • 车载信息娱乐系统接口滤波,适应车内-40℃~+85℃环境;
  • ADAS系统(雷达/摄像头)信号滤波,提升抗干扰能力。

4. 通信设备

  • 路由器/交换机以太网接口滤波,抑制传输共模噪声,提升数据稳定性。

五、选型与使用注意事项

确保性能最大化,需注意:

1. 电流/电压匹配

  • 连续工作电流≤1.2A(留余量),峰值电流不超1.5A;
  • 工作电压≤50V,避免过压损坏。

2. 干扰频段匹配

若干扰频段偏离100MHz,参考同系列低/高阻抗版本,确保抑制效果。

3. 安装工艺

  • 回流焊峰值温度240℃~260℃,时间≤10s,避免高温损伤;
  • 引脚间保持绝缘距离,防止短路。

总结

FRICM-5020-142兼具高效共模抑制、低损耗、宽温工作、紧凑封装优势,覆盖多领域需求,是国产化替代进口滤波器的理想选择。

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
