PCAQ3225A-142S 产品概述

一、产品简介

PCAQ3225A-142S 为谱罗德(PROD)推出的一款双通道共模滤波器,采用表面贴装封装(SMD),外形尺寸为 3.2 × 2.5 × 1.9 mm。器件针对高速信号与电源线的共模干扰抑制而优化,适用于空间受限的消费电子、通信设备和汽车电子低功耗电源滤波场合。

二、主要技术参数

  • 通道数:2(双通道共模)
  • 额定电流:1.5 A(直流连续通过能力)
  • 共模阻抗:1.4 kΩ @ 100 MHz(典型值)
  • 额定电压:60 V
  • 直流电阻(DCR):200 mΩ(典型)
  • 工作温度范围:-25 ℃ ~ +85 ℃
  • 绝缘电阻:≥ 10 MΩ
  • 封装:SMD,尺寸 3.2 × 2.5 × 1.9 mm

三、结构与封装特点

该元件采用紧凑的磁芯与绕组结构,双通道布局使其在单封装内实现两路共模抑制,节省 PCB 面积。表面贴装形式兼容主流回流焊工艺,封装尺寸适用于中小型移动设备、模块化电源和接口滤波器设计。

四、性能特点

  • 高频抑制能力强:在 100 MHz 处典型共模阻抗达到 1.4 kΩ,对常见射频干扰有良好抑制效果,有利于满足 EMI/EMC 要求。
  • 适中电流等级:1.5 A 的额定电流适合中小功率电源与接口电流需求,兼顾滤波效果与温升控制。
  • 低 DCR 损耗:典型 200 mΩ 的直流电阻在导通时引起的功耗和压降较小,有利于提高效率并降低发热。
  • 宽温度与高绝缘:-25~+85 ℃ 的工作温度范围和 ≥10 MΩ 的绝缘电阻,保证在一般工业与民用环境下的可靠性。

五、典型应用场景

  • USB、HDMI 等低压信号线与差分接口的共模干扰抑制
  • 移动设备、平板、便携式电源模块的 EMI 滤波
  • 通讯设备、机顶盒、网络终端等敏感射频电路的输入输出滤波
  • 需要体积受限而又要求良好共模抑制的电源和信号线滤波场合

六、布局与焊接建议

  • 器件应尽量靠近干扰源或进入 PCB 的连接端放置,以提高滤波效果。
  • 输入侧与输出侧走短且对称的走线,尽量避免环路面积增大。
  • 在器件附近设置良好接地平面,并在必要处进行地线过孔连接,以改善高频回流路径。
  • 推荐遵循标准回流焊曲线,避免过高的峰值温度或长时间高温暴露,防止封装和绕组受损。

七、可靠性与测试建议

  • 在设计验证阶段,建议测量器件在目标频带(如 10 MHz~300 MHz)上的共模阻抗曲线,以确认滤波器性能与系统要求匹配。
  • 进行额定电流长期通电升温测试,评估 DCR 引起的温升与热稳定性。
  • 绝缘电阻、耐压及热循环测试可用于验证器件在预期工作环境下的可靠性。

八、选型注意事项

  • 确认目标频段的共模阻抗与系统噪声频谱匹配,避免在关注频率处阻抗不足或过高产生寄生影响。
  • 考虑实际工作电流余量,若电流接近 1.5 A,应选择更高额定电流的器件以降低发热与老化风险。
  • 留意封装尺寸与 PCB 布局空间,确保贴装可靠性与散热条件满足需求。

PCAQ3225A-142S 以小尺寸、高阻抗和适中电流承载能力为特长,适合用于对共模抑制有较高要求且空间受限的电子产品中。

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
