FDCW2012-2-300TF共模滤波器产品概述

FDCW2012-2-300TF是长江微电(cjiang) 推出的0805封装共模滤波器,专为电子设备的电磁干扰(EMI)抑制设计,兼具双通道滤波、低损耗传输与宽温适配特性,适配便携电子、工业控制、物联网等多领域的小型化滤波需求。

一、产品定位与核心属性

该产品属于双通道共模滤波器,核心作用是抑制信号/电源线路中的共模噪声(即两条线路上相位相同、幅值相等的干扰信号),同时保持差模信号(有效传输信号)的低损耗传输。其定位为小型化、中等电流容量的EMI抑制器件,平衡了滤波性能、体积与成本,适合对PCB空间敏感、电流需求适中的设备。

二、关键技术参数详解

1. 共模滤波核心参数

共模阻抗为30Ω@100MHz,这是衡量滤波性能的关键指标:100MHz是电子设备中EMI干扰的高发频段(如射频信号串扰、开关电源高频噪声),30Ω的阻抗可有效衰减该频段内的共模干扰,减少干扰对敏感电路(如传感器、射频模块)的影响。

2. 电流与电压容量

  • 额定电流450mA:支持中等功率的直流/低频信号传输,满足小型电源模块、低速数据总线(如UART、I2C)的电流需求;
  • 额定电压50V:适配5V、12V、24V等常见低压系统,耐压裕量充足,避免过压损坏。

3. 传输损耗与绝缘性能

  • 直流电阻(DCR)200mΩ:双通道均具备低DCR特性,信号传输过程中功率损耗小(计算损耗:(P=I^2R=0.45^2×0.2≈0.04W)),发热低,长期工作稳定性好;
  • 绝缘电阻10MΩ:通道间及通道与封装外壳的绝缘性能可靠,防止漏电或信号串扰,确保各通道独立工作。

4. 环境适应性

工作温度范围为**-40℃~+85℃**,覆盖工业级与消费电子的常见温差场景,可稳定工作于户外、车载辅助电路等环境。

三、封装与物理特性

采用0805封装(公制2012封装,尺寸2.0mm×1.2mm),属于小型化表面贴装(SMD)封装,具备以下优势:

  • 体积紧凑:不占用过多PCB空间,适配智能手机、智能穿戴、物联网传感器等便携/小型化设备;
  • 工艺兼容:支持回流焊、波峰焊等自动化贴装工艺,生产效率高,焊接可靠性强;
  • 无引脚设计:避免引脚断裂风险,适合高密度PCB布局。

四、典型应用场景

该产品的参数特性使其适配以下场景:

  1. 消费电子:智能手机、平板电脑的USB充电线路、音频模块滤波,抑制充电噪声对射频信号的干扰;
  2. 物联网(IoT):传感器节点、低功耗蓝牙模块的电源与信号滤波,保证数据采集准确性;
  3. 工业控制:小型PLC、远程IO模块的辅助电路滤波,适应-40℃~+85℃的宽温环境;
  4. 车载电子:车载信息娱乐系统的低功耗辅助电路滤波(如USB接口、蓝牙模块)。

五、品牌与选型价值

长江微电作为国内知名电子元器件厂商,产品一致性好、供货稳定;FDCW2012-2-300TF在同规格产品中,平衡了滤波性能、电流容量与成本,是替代进口器件的高性价比选择,适合中小批量及大规模生产需求。

综上,FDCW2012-2-300TF凭借双通道滤波、100MHz频段有效抑制、低损耗与宽温特性,成为电子设备EMI抑制的实用选型,适配多领域的小型化滤波需求。

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
