FACT4532-110-2P-T 共模滤波器产品概述

FACT4532-110-2P-T是长江微电(cjiang)针对电子设备电磁干扰(EMI)抑制需求推出的双路SMD共模滤波器,具备紧凑尺寸、宽频滤波能力与高可靠性,适配低压小电流场景的电路设计,可有效降低设备间电磁干扰,满足EMC认证要求。

一、核心参数全面梳理

该产品的核心参数围绕“滤波性能、电气安全、环境适应性”三大维度设计,具体如下:

1. 电气核心参数

  • 通道数:2通道(双路对称设计),可同步对电源正负极或双路信号进行共模滤波;
  • 电感特性:11μH@100kHz(典型工作频率下的共模电感量,针对开关电源、射频电路的中低频干扰);
  • 电流电压:额定电流250mA(持续工作电流上限,适配小功率设备),额定电压50V(直流/交流工作范围,覆盖5V~48V常见低压场景);
  • 直流损耗:直流电阻(DCR)600mΩ(单通道内阻,低损耗设计减少功率消耗,提升电池设备续航)。

2. 阻抗与绝缘特性

  • 阻抗覆盖:600Ω@10MHz(高频段高阻抗,抑制10MHz左右的射频干扰);
  • 绝缘性能:绝缘电阻≥10MΩ(DC500V测试条件下),保障通道间及通道与地的绝缘安全,防止漏电或短路。

3. 环境与封装参数

  • 工作温度:-40℃~+125℃(宽温范围,适应工业级、户外及高温散热环境);
  • 封装规格:SMD-4P(4引脚贴片封装),尺寸4.5mm×3.2mm(超小体积,节省PCB空间,适配高密度设计)。

二、设计特点与性能优势

该产品通过优化磁芯材料与绕线工艺,实现“小体积、宽频滤波、低损耗”的平衡:

1. 紧凑贴片封装,适配高密度设计

4.5×3.2mm的超小尺寸+4引脚SMD封装,可直接集成于便携设备、小型模块的PCB中,无需额外占用大量空间,尤其适合智能手机、智能手表等紧凑产品。

2. 宽频EMI抑制,覆盖中高频干扰

  • 中低频段(100kHz左右):11μH电感量有效抑制开关电源、DC-DC转换器的共模噪声;
  • 高频段(10MHz左右):600Ω高阻抗抑制射频电路、无线通信的电磁干扰,满足CE、FCC等EMC认证要求。

3. 低损耗设计,提升能效

600mΩ的低DCR减少电流通过时的功率损耗,尤其适合电池供电的便携设备(如蓝牙耳机、智能手环),延长单次充电续航时间。

4. 双路同步滤波,简化电路设计

2通道对称设计,无需额外并联多路滤波器,可同时对电源正负极或双路信号进行共模滤波,降低电路复杂度与BOM成本。

三、典型应用场景

结合参数特性,该产品主要适配以下低功耗、小空间需求的场景:

1. 便携电子设备

智能手机、智能手表、蓝牙耳机、运动手环等电池供电设备,用于抑制充电电路、射频模块的EMI,避免干扰自身或周边设备。

2. 小型工业与IoT模块

  • 工业传感器(如温度、压力传感器)、PLC IO接口模块,抑制工业环境中的电磁干扰;
  • 智能家居节点(如智能灯泡、传感器)、物联网终端,提升通信稳定性,减少误码率。

3. 小功率消费电子配件

  • 5V/12V小功率电源适配器、USB充电器,满足EMC认证;
  • USB-HUB、蓝牙适配器等配件,抑制信号干扰。

四、可靠性与安装注意事项

1. 可靠性保障

  • 宽温稳定性:-40℃~+125℃工作温度范围,磁芯与导线性能稳定,无参数漂移;
  • 机械可靠性:SMD封装焊接可靠性高,抗振动、抗冲击能力符合电子元器件行业标准,适配移动设备或工业振动环境。

2. 安装与焊接建议

  • 焊接工艺:采用回流焊(峰值温度240℃~260℃,时间≤30秒),避免手工焊接过热损坏磁芯;
  • PCB设计:焊盘尺寸匹配封装规格,滤波电路需靠近干扰源(如开关电源)或敏感电路(如射频模块),提升滤波效果;
  • 极性说明:双路对称设计,无引脚极性要求,安装无需区分顺序。

五、总结

FACT4532-110-2P-T共模滤波器凭借“小体积、宽频滤波、低损耗、高可靠性”的核心优势,成为便携设备、小型工业模块、消费电子等场景中抑制EMI的理想选择,可有效提升设备的电磁兼容性与工作稳定性,适配多类低压小电流应用需求。

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.
