FDCW2012-2-301TF共模滤波器产品概述

一、产品基本属性与定位

FDCW2012-2-301TF是长江微电(cjiang)推出的0805封装双通道共模滤波器,核心作用是抑制电子电路中的共模电磁干扰(EMI),同时保障信号传输完整性。该产品针对小电流、中低电压的信号线路设计,兼顾干扰抑制性能与空间利用效率,适用于消费电子、通信设备、工业控制等多领域的电路EMI优化。

二、核心技术参数详解

产品关键参数直接体现性能定位,核心指标如下:

  1. 共模阻抗:300Ω@100MHz——针对100MHz频段(消费电子、通信设备常见EMI干扰集中区)提供精准衰减,有效降低对外辐射干扰与线路串扰;
  2. 额定电流:290mA——满足小功率信号线路(如音频、低速数字信号、传感器信号)的电流承载需求,避免过载;
  3. 额定电压:50V(直流/交流峰值)——保障线路绝缘安全,适配多数低压电路的电压范围;
  4. 直流电阻(DCR):400mΩ——低直流损耗,减少信号衰减与发热,不影响信号传输质量;
  5. 绝缘电阻:≥10MΩ——通道间及通道与地绝缘性能良好,避免信号串扰;
  6. 工作温度范围:-40℃~+85℃——宽温适应性,可用于低温环境(如北方户外设备)或高温环境(如设备内部散热区)。

三、封装与尺寸规格

采用0805英寸(对应公制2012)贴片封装,典型尺寸为:长度2.0±0.2mm,宽度1.2±0.2mm,高度0.8±0.2mm。该封装优势在于:

  • 体积紧凑,适合高密度PCB设计(如智能手机、小型路由器等紧凑设备);
  • 贴片式安装,支持自动化贴装,生产效率高;
  • 无引线设计,减少寄生参数,进一步优化信号传输。

四、典型应用场景

FDCW2012-2-301TF的参数特性适配以下场景:

  1. 消费电子:手机、平板的音频接口滤波(抑制电磁干扰对音质的影响)、USB数据线共模干扰抑制;
  2. 通信设备:路由器、交换机的10/100M以太网端口共模噪声抑制,保障数据传输稳定性;
  3. 工业控制:传感器信号线路(如温度、压力传感器)、PLC的小电流控制信号滤波,避免工业环境干扰;
  4. 小功率电源滤波:DC-DC转换电路的输入/输出端共模噪声抑制,减少电源纹波对负载的影响;
  5. 车载电子(低高温区):车载中控屏、行车记录仪的信号线路滤波(适配-40~+85℃的车载环境)。

五、性能优势与设计价值

  1. 精准干扰抑制:300Ω@100MHz的共模阻抗针对主流干扰频段,比通用滤波器更具针对性;
  2. 信号完整性保障:低DCR(400mΩ)与高绝缘电阻减少信号衰减与串扰,适合模拟/数字信号传输;
  3. 空间与成本平衡:0805封装节省PCB空间,同时单通道成本低于多通道拆分方案;
  4. 环境适应性强:宽温范围与高绝缘电阻,降低恶劣环境下的失效风险。

六、可靠性与安全特性

该产品通过以下设计保障可靠性:

  • 绝缘电阻≥10MΩ,满足UL、CE等安全标准的绝缘要求;
  • 工作温度范围覆盖工业级与消费级场景,长期使用参数稳定;
  • 贴片封装采用耐高温材料,贴装过程中无变形、开裂风险;
  • 额定电流与电压留有余量,避免过载损坏。

该产品是小电流信号线路EMI优化的高性价比选择,兼顾性能、体积与可靠性,可有效提升电子设备的电磁兼容性。

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
