FDCW3216-2-261TF共模滤波器产品概述

一、产品核心定位与功能

FDCW3216-2-261TF是长江微电(cjiang)推出的2通道贴片式共模滤波器,专为低功耗电路的电磁干扰(EMI)抑制设计。其核心功能是通过对共模噪声的定向衰减,减少信号传输中的干扰,同时保持差模信号的完整性,适配对体积、功耗、温宽有严格要求的电子设备。

二、关键性能参数深度解析

该产品的参数精准匹配多数低压小电流电路的EMI需求,具体解析如下:

  1. 通道与滤波针对性:2通道设计可同时过滤差分信号(如USB、I2C)的两路信号,无需额外并联器件,简化PCB布局;
  2. 核心阻抗特性:260Ω@100MHz,针对100MHz频段(电子设备EMI干扰集中区)提供有效衰减,能显著降低信号传输中的共模噪声;
  3. 电流与电压耐受:额定电流310mA(连续工作),满足摄像头、传感器等低功耗设备的电流需求;额定电压50V,覆盖多数低压电路范围,避免击穿风险;
  4. 损耗与信号完整性:直流电阻(DCR)仅500mΩ,直流损耗极低,不会明显影响信号传输质量,适配高速/低速信号;
  5. 环境适应性:工作温度-40℃~+125℃,宽温设计可适应车载、工业等恶劣环境;绝缘电阻10MΩ,保证电气绝缘,防止短路漏电。

三、封装与可靠性设计

  1. 封装规格:采用1206贴片封装(3.2mm×1.6mm),体积小巧,兼容回流焊、波峰焊等主流工艺,适合高密度PCB布局;
  2. 工艺可靠性:基于长江微电成熟磁芯绕线工艺,磁芯材料适配宽温环境,避免高低温性能衰减;焊接端抗氧化设计,减少虚焊风险;
  3. 绝缘防护:封装内外绝缘设计满足10MΩ要求,防止通道间或通道与地短路,提升电路安全性。

四、典型应用领域

该产品因参数匹配性好、体积小、温宽宽,主要应用于:

  1. 汽车电子:车载摄像头、TPMS传感器、显示屏的信号线路(如LVDS、I2C),过滤行驶中的电磁干扰;
  2. 消费电子:手机、平板、笔记本的USB接口、音频接口,抑制数据传输与充电的EMI噪声;
  3. 工业控制:小型PLC、传感器节点的通信线路(如RS485、CAN),适应工业现场高低温与电磁环境;
  4. 通信设备:蓝牙、WiFi模块的天线/数据接口,减少信号干扰。

五、使用注意事项

为保证性能与可靠性,需注意:

  1. 焊接规范:回流焊温度≤260℃,时间≤10秒;波峰焊温度≤240℃,避免损坏磁芯;
  2. 电气限制:连续电流≤310mA(峰值需控制),电压≤50V,防止磁芯饱和或绝缘击穿;
  3. 布局建议:靠近信号接口端,减少噪声耦合;共模地正确连接系统地,避免虚地;
  4. 存储条件:常温(15℃~35℃)、干燥(湿度≤60%)环境,避免潮湿影响绝缘。

该产品平衡了滤波性能、体积与可靠性,是低功耗电路EMI抑制的高性价比选择。

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
