TDK YFF18SC1H222MT0H0N 馈通电容滤波器产品概述

一、产品定位与核心特性

TDK YFF18SC1H222MT0H0N是一款小型化SMD馈通电容滤波器,专为电子设备的电磁干扰(EMI)/射频干扰(RFI)抑制设计,属于TDK陶瓷电容产品线中的高可靠性型号。其核心特性可概括为:

  • 穿心式结构:信号路径与接地平面隔离,大幅降低共模干扰耦合;
  • 低功耗设计:300mΩ直流电阻(DCR)减少电流损耗与发热;
  • 宽温适配:-55℃~+125℃覆盖工业/汽车级环境;
  • 高电流能力:1A额定电流适配中小功率电路;
  • 微型封装:0603(1608公制)尺寸仅0.8×1.6mm,适合高密度PCB设计。

二、关键参数详解

1. 容值与精度

标称容值2.2nF(代码“222”),精度±20%,属于工业级常用容差范围,可满足大多数EMI滤波场景的偏差要求(如电源线路的低频干扰抑制)。

2. 额定电压

50V直流(或峰值交流),可稳定工作在50V以下的直流电路(如5V/12V电源)或峰值电压≤50V的交流电路中,适配常见低压系统。

3. 额定电流

1A持续电流,支持中小功率电路的滤波需求(如USB接口供电、传感器节点电源),避免大电流下器件过热。

4. 直流电阻(DCR)

仅300mΩ,低电阻设计显著降低功耗(1A电流下损耗仅0.3W),减少热积累对器件寿命的影响。

5. 工作温度范围

-55℃+125℃,覆盖工业环境(-40+85℃)、汽车环境(-40~+125℃)等典型场景,可靠性更高。

三、封装与安装适配

1. 封装规格

采用0603(1608公制)SMD-4P封装,尺寸为0.8mm(宽)×1.6mm(长),厚度符合SMD器件标准(约0.6mm),适配自动化贴装工艺。

2. 引脚设计

4引脚SMD结构(两端各2个引脚),信号引脚连接线路,接地引脚与PCB接地平面焊接,实现“穿心式”滤波——信号通过器件内部,干扰被接地端吸收。

3. 应用适配

无需穿孔,直接表面贴装于PCB,适配单端信号(如电源线)或差分信号(如USB数据)的滤波,兼容常见PCB布局。

四、可靠性与环境适应性

1. 温度稳定性

在-55℃~+125℃范围内,容值变化符合TDK陶瓷电容的温度特性(典型温度系数≤±15%),滤波性能无明显波动。

2. 机械可靠性

陶瓷基片封装抗振动/冲击性能优异,符合电子元器件行业标准(如MIL-STD-202),适合车载、工业等振动环境。

3. 寿命特性

基于TDK成熟的MLCC工艺,在额定参数下工作寿命可达10万小时以上,满足长期使用需求。

五、典型应用场景

1. 消费电子

智能手机、平板的USB/HDMI接口滤波,抑制电磁辐射(符合FCC/CE认证要求);笔记本电脑电源线路的共模干扰抑制。

2. 汽车电子

车载信息娱乐系统(车机、导航)的电源滤波;ADAS传感器(摄像头、毫米波雷达)的信号滤波,满足汽车级温度与可靠性标准。

3. 工业控制

PLC、工业传感器节点的电源滤波;Modbus/Profinet通信模块的EMI抑制,减少工业环境中的电磁干扰。

4. 通信设备

路由器、交换机的射频信号滤波;基站电源线路的浪涌与干扰抑制,提升通信质量。

5. 医疗电子

便携式监护仪、血糖仪的信号滤波,符合低干扰、高可靠性要求(如IEC 60601医疗标准)。

TDK YFF18SC1H222MT0H0N凭借小型化、高可靠性与宽温适配性,成为消费电子、汽车、工业等领域EMI滤波的优选器件,可有效提升设备的电磁兼容性(EMC)。

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
