FDCW3216-2-222TF 产品概述

一、概述

FDCW3216-2-222TF 为长江微电(cjiang)推出的一款双通道表面贴装共模滤波器,专为抑制高速信号线的共模干扰设计。该器件在100MHz时呈现约2.2kΩ的共模阻抗,额定工作电流200mA、额定电压50V,适用于各种低功耗信号通路的电磁兼容(EMC)处理。封装为1206(公制尺寸3216),直流电阻(DCR)低至1.2Ω,工作温度范围为-40℃~+125℃,绝缘电阻≥10MΩ。

二、主要性能参数

  • 通道数:2(双线共模)
  • 共模阻抗:2.2kΩ @ 100MHz
  • 额定电流:200mA(连续)
  • 额定电压:50V
  • 直流电阻(DCR):1.2Ω(典型)
  • 工作温度:-40℃ ~ +125℃
  • 绝缘电阻:≥10MΩ
  • 封装:1206(3216mm)

三、典型应用场景

  • 高速信号线的共模干扰抑制(如差分对的共模滤波)
  • 通讯与数据接口(低电流USB、串行总线、传感器接口等)
  • 消费电子与便携设备中对EMI要求较高的信号链路
  • 智能终端、测量仪器、工业控制中的噪声治理

四、封装与焊接建议

器件采用标准1206贴片封装,适合自动贴装与回流焊工艺。建议按照制造商提供的推荐焊盘尺寸设计PCB,采用符合行业标准的回流焊温度曲线进行焊接。贴装时注意避免过大机械应力,存储与回流后建议进行外观与电性能在线检测。

五、使用要点与工程注意事项

  1. DC偏置影响:共模滤波器在施加直流偏置时共模阻抗会下降,设计时应考虑直流电流对抑制效果的影响并留有裕量。
  2. 电流与温升:额定200mA为连续工作限值,长期接近额定电流会带来温升与电性能漂移,必要时应做热仿真或实测验证。
  3. 布局建议:靠近噪声源或连接器端放置以提高抑制效果;差分线对应保持对称走线并在滤波前后做好阻抗匹配与接地处理。
  4. ESD与过压防护:该器件主要用于滤波,不具备明显的过压保护功能,系统中仍需配置相应保护元件以防异常高压或浪涌。
  5. 测试与筛选:推荐在样机阶段测量共模阻抗曲线、DCR与绝缘电阻,确保满足系统规格。

六、可靠性与采购建议

FDCW3216-2-222TF 面向对尺寸与性能有较高集成要求的应用,适用温度范围及绝缘指标满足一般工业级应用。采购时建议向长江微电索取完整规格书(Datasheet)、电气特性曲线、回流焊工艺说明及可靠性测试报告,以便进行可靠性验证与批量生产导入。订购请使用完整料号:FDCW3216-2-222TF(品牌:cjiang / 长江微电)。

如需进一步的阻抗曲线、封装图或参考电路建议,可联系供应商或索取样品进行实测验证。

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
