FDCW2012-2-102TF 共模滤波器 产品概述

一、产品简介

FDCW2012-2-102TF 是长江微电(cjiang)推出的一款用于抑制共模干扰的贴片共模滤波器,采用 0805 表面贴装封装。该器件针对中高频共模噪声抑制进行了优化,适用于空间受限的消费电子和通信终端,用以改善电磁兼容(EMC)性能并保证差分信号完整性。

二、核心参数

  • 型号:FDCW2012-2-102TF
  • 品牌:cjiang(长江微电)
  • 通道数:2(双通道/差分两线)
  • 阻抗:1 kΩ @ 100 MHz(共模阻抗)
  • 额定电流:100 mA
  • 额定电压:50 V
  • 直流电阻(DCR):1 Ω
  • 工作温度:-40 ℃ ~ +85 ℃
  • 绝缘电阻:≥10 MΩ
  • 封装:0805(适配常见 SMT 贴装工艺)

三、主要特性

  • 在 100 MHz 附近提供高达 1 kΩ 的共模阻抗,有效抑制射频段共模干扰。
  • 低直流电阻(约 1 Ω),对直流偏置和低频差模信号影响小,保证信号传输质量。
  • 额定电流 100 mA、额定电压 50 V,适合弱电信号线和低电流电源线路的 EMI 处理。
  • 宽温度工作范围,适应工业与民用环境。
  • 0805 尺寸利于尺寸受限电路板的布局与自动化贴装。

四、典型应用场景

  • USB、串行总线或低速差分信号线的共模干扰抑制(注意确认电流与速率匹配)。
  • 手机、平板、蓝牙、Wi‑Fi 等移动终端中用于改善 EMC 表现的信号滤波。
  • 传感器接口、音频线路、摄像头接口等对共模噪声敏感的信号链。
  • 工业控制与测量设备中的低电流信号线干扰抑制。

五、选型与使用注意

  • 核心指标匹配:确认目标频段的共模噪声频谱是否覆盖器件标称的 100 MHz 附近阻抗峰值;若噪声主频不同请参考厂方更详细的频率响应曲线。
  • 电流与电压裕度:额定电流 100 mA 与额定电压 50 V 适合弱电场景;对于高电流或电源线路应选择额定值更高的器件。
  • 直流偏置影响:实际工作中直流偏置电流会降低磁芯饱和前的共模阻抗,设计时应考虑偏置条件下的性能变化。
  • 布局建议:将滤波器尽量靠近干扰源或外部连接器放置,保持差分两线对称布线,避免在滤波器两端形成大回路面积。
  • 生产工艺:0805 封装兼容常用回流焊工艺,具体焊接温度曲线建议参照厂方资料确认。

六、可靠性与包装

  • 工作温度范围 -40 ℃ 至 +85 ℃,适应一般工业与民用环境。
  • 绝缘电阻 ≥10 MΩ,具备良好的绝缘性能。
  • 封装 0805 便于自动化贴装与检验;常规供货形式为卷带(具体包装方式请向供应商确认)。
  • 建议在样机阶段进行实际温湿度、振动及长期老化等可靠性评估,以验证在目标应用环境中的长期稳定性。

总结:FDCW2012-2-102TF 为一款面向中高频共模抑制的小型 SMT 共模滤波器,适用于空间受限的弱电信号线路,通过合理选型与布板能够显著提升电路系统的 EMC 表现。如需进一步的阻抗频响曲线、封装尺寸图或回流焊工艺建议,请向厂方索取详细数据手册。

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
