FDCW3216-2-500TF共模滤波器产品概述

FDCW3216-2-500TF是长江微电(cjiang)推出的贴片式共模滤波器,采用1206(公制3216)封装,针对高频信号线路的共模干扰抑制设计,具备宽温适应性、低损耗等核心优势,广泛适用于消费电子、工业控制、车载通信等领域的EMC/EMI优化需求。

一、核心电气参数与性能解析

该产品的参数设计围绕共模干扰衰减与信号完整性平衡展开,关键指标及意义如下:

1. 滤波核心指标

  • 通道数2:适配差分信号传输(如USB、LVDS),可同时对两路信号进行共模滤波,无需额外并联器件;
  • 共模阻抗50Ω@100MHz:100MHz频段共模干扰的抑制能力核心——与射频/高速数字系统的50Ω阻抗环境精准匹配,能有效衰减共模干扰(如电磁辐射、线路串扰),同时不影响差模信号传输;
  • 直流电阻(DCR)250mΩ:每通道低直流电阻,减少信号传输功率损耗,保障信号完整性(尤其适合低功耗场景)。

2. 电气安全参数

  • 额定电流400mA:持续工作允许的最大直流电流,满足一般小功率信号线路(如传感器、数据接口)的电流需求;
  • 额定电压50V:直流耐压安全值,覆盖多数低压电子系统的工作电压范围;
  • 绝缘电阻10MΩ:引脚间及引脚与外壳的绝缘性能可靠,避免不同线路串扰,保障电气安全。

3. 环境适应性

  • 工作温度-40℃~+125℃:宽温设计可适应工业级(户外传感器)、车载级(ADAS系统)等严苛环境,无需额外散热防护。

二、封装与物理特性

FDCW3216-2-500TF采用1206贴片封装(典型尺寸3.2mm×1.6mm×1.0mm),具备三大优势:

  1. 体积紧凑:适合高密度PCB布局,节省终端产品内部空间(如智能手机、小型路由器);
  2. 自动化贴装:符合SMT工艺要求,可通过回流焊快速批量组装,降低生产复杂度;
  3. 低寄生电感:无引线设计减少高频寄生效应,进一步优化滤波性能。

三、典型应用场景

结合参数特性,该产品主要覆盖以下场景:

  1. 高速数字接口:USB 2.0/3.0、HDMI、LVDS等差分端口的共模干扰抑制,避免信号失真;
  2. 消费电子:智能手机、平板、笔记本的充电/数据接口滤波,提升电磁兼容性;
  3. 工业控制:PLC通信线路、温度/压力传感器接口的抗干扰,保障工业现场数据稳定;
  4. 车载电子:车载信息娱乐系统、ADAS的信号滤波,适应车载宽温与振动环境;
  5. 通信设备:小型基站、家用路由器的射频/数字信号滤波,减少电磁辐射干扰。

四、设计优势与使用注意事项

1. 产品核心优势

  • 滤波与信号完整性平衡:共模抑制能力强,低DCR减少差模信号损耗;
  • 宽温可靠性:-40~125℃满足多行业严苛环境;
  • 高性价比:长江微电成熟工艺保障性能稳定,成本优于同规格进口器件。

2. 使用注意事项

  • 电流限制:线路工作电流需低于400mA,避免过载过热;
  • 阻抗匹配:建议应用于50Ω阻抗系统,发挥最佳滤波效果;
  • 焊接工艺:回流焊峰值温度≤260℃,焊接时间≤10秒,避免封装损坏;
  • 布局建议:滤波器尽量靠近信号输入/输出端口,减少干扰耦合路径。

FDCW3216-2-500TF作为长江微电的主流共模滤波器,凭借精准阻抗匹配、宽温适应性和小体积设计,成为电子系统EMC设计中解决共模干扰的可靠选择,覆盖从消费电子到工业级的多场景需求。

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.

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
