FACT3225-510-2P-T 共模滤波器产品概述

FACT3225-510-2P-T是长江微电(cjiang)推出的一款小型化贴片式共模滤波器,针对低功耗电子设备的电磁干扰(EMI)抑制需求设计,具备宽温适配、低损耗、高阻抗等核心优势,可有效解决开关电源、数据接口等场景中的共模噪声问题,助力设备满足EMC合规要求。

一、产品定位与核心功能

共模滤波器的核心作用是衰减共模噪声(即两条传输线中相位相同、流向一致的干扰电流),同时不影响差模信号(正常传输的有用信号)。FACT3225-510-2P-T定位为小电流、宽温型贴片共模滤波器,专为低功耗电子设备(如智能穿戴、小型消费电子)的EMI/EMC设计,重点解决开关电源纹波、高速数据传输干扰等常见问题,确保信号完整性与电磁兼容性。

二、关键技术参数深度解析

产品参数围绕“噪声抑制、可靠性、小型化”三大核心需求设计,关键指标如下:

  1. 电感与阻抗特性
    核心电感值为51uH@100kHz(对应开关电源常见共模噪声频率),配合2.6kΩ@10MHz的高频阻抗,实现宽频段噪声覆盖——从100kHz(电源纹波)到10MHz(USB/蓝牙等高速接口干扰)的常见干扰均能有效抑制,满足多场景EMC要求。
  2. 电气额定值
    • 额定电流200mA:支持低功耗设备的持续工作电流(如智能穿戴充电模块);
    • 额定电压50V:满足常规低压系统(3.3V~24V)的绝缘耐压需求;
    • 直流电阻(DCR)700mΩ:低损耗设计减少功率消耗,降低设备发热,提升效率。
  3. 可靠性参数
    • 绝缘电阻≥10MΩ:保证电气绝缘安全,避免短路风险;
    • 工作温度-40℃~+125℃:宽温设计适配极端环境(如车载低温启动、高温工作),可靠性符合工业/汽车级要求。

三、封装与结构设计优势

采用SMD-4P 3.2x2.5mm小型贴片封装,具备三大设计优势:

  1. 小型化适配:体积紧凑(仅3.2×2.5mm),符合电子设备轻薄化趋势,可集成于PCB高密度布局;
  2. 安装便捷:4引脚贴片设计支持自动化贴装(SMT),提升生产效率,降低人工成本;
  3. 性能稳定:封装结构优化了寄生电容与电阻,减少信号损耗,保证滤波效果的一致性与长期可靠性。

四、典型应用场景

产品适用于以下低功耗电子设备的EMI抑制:

  1. 智能穿戴:智能手表、手环的充电模块、蓝牙/USB接口的噪声过滤,避免无线信号与电源干扰;
  2. 消费电子:智能手机、平板电脑的Type-C接口、充电电路的EMC防护,满足国际认证要求;
  3. 小型工业设备:传感器节点、低功耗PLC模块的电源滤波,避免工业环境电磁干扰影响信号精度;
  4. 车载子系统:胎压监测(TPMS)、车载蓝牙模块的EMC防护,适配汽车级宽温环境(-40℃~+125℃)。

五、品牌与品质保障

长江微电(cjiang)作为国内专业电感制造商,为产品提供完善品质保障:

  • 原材料管控:采用优质锰锌磁芯与高导电率导线,保证电感性能稳定;
  • 可靠性测试:通过温湿度循环、振动冲击、耐电压等测试,符合GB/T 12798、IEC 61000等行业标准;
  • 环保合规:符合RoHS、REACH指令,满足全球市场准入要求。

FACT3225-510-2P-T凭借紧凑封装、宽温适配、低损耗等优势,成为小电流电子设备EMI抑制的优选方案,可有效帮助设备通过EMC认证,提升产品竞争力。

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
