FDCW3216-2-102TF共模滤波器产品概述

FDCW3216-2-102TF是长江微电(cjiang)推出的一款小型化表面贴装共模滤波器,采用1206(公制3216)封装,针对低压小电流场景的共模干扰抑制需求设计,兼顾滤波性能、体积紧凑性与宽温可靠性,适用于消费电子、通信、工业控制等多领域。

一、产品核心定位与价值

共模滤波器的核心作用是抑制电路中共模干扰(两条信号线同时携带的同向干扰信号),避免其影响信号传输质量或造成设备误触发。FDCW3216-2-102TF定位于小电流双路信号滤波,通过优化磁芯材料与绕组设计,在1206紧凑封装内实现高频段(100MHz)的高效干扰抑制,同时控制直流损耗与成本,满足高密度PCB设计的轻量化、小型化需求。

二、关键参数深度解析

该产品的核心参数直接决定应用适配性,具体解析如下:

1. 通道与电流容量

  • 2通道设计:支持双路差分信号(如USB、差分数据线)的同步滤波,避免单通道滤波时的信号不平衡问题;
  • 230mA额定电流:满足多数低压电路(5V、12V系统)的小电流信号传输需求,如充电接口、传感器信号等,无需额外降额设计。

2. 滤波性能指标

  • 阻抗1kΩ@100MHz:共模滤波器的阻抗是衡量干扰抑制能力的关键指标,1kΩ的阻抗在100MHz频段可有效衰减共模干扰,提升信号纯度;
  • 直流电阻(DCR)1Ω:低直流电阻确保信号的直流损耗极小,不影响原始信号的幅值与完整性,适合对信号损耗敏感的场景(如音频、射频信号)。

3. 电气安全与可靠性

  • 50V额定电压:覆盖常见低压系统的工作电压范围,满足多数消费电子、工业设备的电气安全要求;
  • 绝缘电阻10MΩ:通道间及对地绝缘性能可靠,防止漏电或信号串扰,符合EMC设计规范;
  • 工作温度-40℃~+125℃:宽温范围适应严苛环境,如车载电子的高温工况、户外设备的低温场景,无需额外散热或防护设计。

三、封装与工艺设计优势

FDCW3216-2-102TF采用1206表面贴装封装(尺寸3.2mm×1.6mm),具备以下设计优势:

  1. 小型化适配高密度PCB:1206封装体积紧凑,可大幅节省PCB空间,适合智能手机、智能穿戴等便携设备的内部布局;
  2. 自动化贴装兼容性:表面贴装设计支持高速SMT生产线,降低生产难度与成本;
  3. 宽温材料选型:磁芯采用耐高温铁氧体材料,绕组选用耐高低温的漆包线,确保宽温范围内性能稳定,无参数漂移。

四、典型应用场景

该产品的参数特性使其适用于以下场景:

  1. 消费电子终端:智能手机、平板的充电接口(Type-C)、音频接口,抑制充电纹波与电磁干扰,减少杂音;
  2. 通信模块:WiFi、蓝牙、LoRa等无线模块的天线接口,衰减射频共模干扰,提升信号传输距离与稳定性;
  3. 工业控制设备:PLC、传感器的信号接口,抑制工业现场的电磁噪声,确保传感器数据准确传输;
  4. 车载电子:车载信息娱乐系统的USB接口、CAN总线接口,适应-40℃~+125℃的车载环境,提升系统抗干扰能力。

五、选型优势总结

对比同类1206封装共模滤波器,FDCW3216-2-102TF具备以下选型优势:

  1. 性能与体积平衡:1206小封装内实现1kΩ@100MHz的滤波能力,兼顾紧凑性与抗干扰性;
  2. 宽温可靠性:覆盖-40℃~+125℃,无需额外环境防护,降低系统设计复杂度;
  3. 低损耗信号传输:1Ω DCR确保信号完整性,适合对损耗敏感的应用;
  4. 品牌成熟度:长江微电的标准化产品,质量稳定,供货周期可控,适合批量生产需求。

综上,FDCW3216-2-102TF是一款高性价比的小电流共模滤波器,可有效解决多场景下的共模干扰问题,是便携设备、通信模块等领域的理想选型。

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.
