FDCW3216-2-900TF 共模滤波器产品概述

FDCW3216-2-900TF是长江微电(cjiang) 推出的1206封装双路共模滤波器,针对100MHz频段共模电磁干扰(EMI)优化设计,兼具小体积、宽温适应性与低损耗特性,适用于低功耗通信、传感器接口等高密度电子系统,可有效提升电路电磁兼容性(EMC)。

一、产品基本定位与核心功能

该器件属于双路共模滤波器件,核心作用是抑制电路中传输的共模干扰(即两条信号线上同时出现的同相干扰),同时保留差模信号(有用信号)的传输。与普通电感不同,共模滤波器通过双绕组的磁耦合特性,对共模噪声呈现高阻抗,对差模信号阻抗极低,从而实现“滤干扰、保信号”的平衡。

二、关键性能参数详解

1. 共模滤波核心指标

  • 共模阻抗:90Ω@100MHz:这是衡量滤波能力的核心参数——100MHz是射频通信、高速数字电路中常见的干扰敏感频段,90Ω的共模阻抗可有效衰减该频段的共模噪声,满足多数电子设备的EMC认证需求;
  • 通道数:2路:支持双路信号(如差分线、双路并行线)的同步滤波,无需额外并联器件,简化电路设计。

2. 电气承载能力

  • 额定电流:370mA(连续):可满足低功耗电路的电流需求(如蓝牙模块、传感器模块的工作电流通常在100mA以内,留有充足余量);
  • 额定电压:50V:适用于低压直流/交流电路(如3.3V、5V、12V系统),电压耐受范围覆盖常规消费电子与工业低压场景;
  • 直流电阻(DCR):300mΩ/通道:低DCR可减少信号传输中的功率损耗,避免有用信号因电阻发热而衰减,保障信号完整性。

3. 绝缘与可靠性参数

  • 绝缘电阻:10MΩ:引脚间及引脚与外壳的绝缘性能稳定,可防止短路或漏电故障,提升电路安全性;
  • 工作温度:-40℃~+125℃:宽温范围支持工业级(-40~+85℃)、车载级(部分场景)及极端环境下的稳定工作。

三、封装与尺寸规格

FDCW3216-2-900TF采用1206表面贴装封装(英制尺寸,对应公制3216,型号中“3216”已体现),标准尺寸为3.2mm×1.6mm×1.0mm,具有以下优势:

  • 小体积适配高密度PCB布局,满足智能穿戴、智能家居等小型化设备的空间需求;
  • 表面贴装工艺兼容常规回流焊/波峰焊,生产效率高,适合批量制造。

四、典型应用场景

结合参数特性,该器件主要适用于以下场景:

  1. 低功耗无线通信模块:蓝牙5.0、Wi-Fi 4(802.11n)、ZigBee等模块的射频接口滤波,抑制发射/接收过程中的共模干扰;
  2. 传感器接口电路:工业温度/压力传感器、医疗生理信号传感器的信号传输线滤波,减少环境电磁噪声对弱信号的干扰;
  3. 中速数字接口:USB2.0、SPI、I2C等接口的共模噪声抑制,保障数据传输的准确性;
  4. 小型电子终端:智能手表、智能家居网关、车载小屏控制器等设备的EMC优化,满足认证要求。

五、品牌与选型价值

长江微电(cjiang)作为国内被动元器件龙头企业,产品通过ISO9001、RoHS等认证,质量稳定可靠;FDCW3216-2-900TF针对100MHz频段的参数优化,避免了“宽频但无针对性”的滤波短板,同时小体积、宽温、低损耗的组合,相比进口同类产品具有更高性价比,是中小批量电子设计的优选方案。

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
