PCAQ1211MW-202 产品概述

一、产品简介

PCAQ1211MW-202 是谱罗德(PROD)推出的一款表面贴装式共模滤波器,适用于双通道线路的共模干扰抑制。器件额定电流为4A,额定电压与耐电压均为125V,适配一般低压电源及信号线的电磁兼容(EMC)处理需求。封装尺寸为12.0 × 10.8 × 6.4 mm,体积紧凑,便于高速线路与开关电源的板级布局。

二、主要性能特点

  • 共模阻抗:2 kΩ @ 100 MHz,提供在高频段显著的共模抑制能力,有效减小开关频率及其谐波引起的干扰。
  • 额定电流:4 A,低损耗设计可满足中大电流路径的应用需求。
  • 直流电阻(DCR):24 mΩ,确保在通过电流时产生的压降与发热最小化,提升系统效率。
  • 绝缘性能:绝缘电阻 ≥ 10 MΩ,耐电压125V,保证线间电隔离性能可靠。
  • 工作温度范围:-25 ℃ ~ +125 ℃,适应多数商业与工业环境。

三、典型应用场景

适用于需抑制共模干扰的双通道电源和信号线,典型应用包括但不限于:

  • 开关电源输入滤波与EMI符合性设计;
  • 通信设备、网关与基站的干扰抑制;
  • 工业控制与仪器仪表的电磁兼容处理;
  • 家用电器与电源适配器中的线缆滤波。

四、封装与 PCB 布局建议

器件为 SMD 封装(12×10.8×6.4 mm),建议贴片在干扰源与接口之间靠近接口侧放置,以缩短共模回路环路,增强滤波效果。布线时保证两路线对称通过器件,地线回流路径应尽量短且低阻,以避免将共模能量转为差模辐射。对于接近额定电流使用场景,需考虑散热与周边元件留有足够空隙。

五、使用注意事项

  • 长时间承载接近额定电流时应校验器件温升,必要时留取热管理空间;
  • 器件为共模滤波结构,不能替代差模电感或变压器在隔离、变比等功能上的作用;
  • 适配高压或汽车级环境时,请确认是否需要更高耐压或满足专项认证(例如AEC-Q)器件。

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
