PSCIAQ3225-101Z — 共模滤波器产品概述

一、产品简介

PSCIAQ3225-101Z(品牌:PROD / 谱罗德)是一款双通道(2 通道)表面贴装共模滤波器,采用 SMD-4P 封装,外形尺寸 3.2 × 2.5 mm。该器件在 100 kHz 时呈现 100 µH 共模电感,标称额定电压 80 V(直流/交流均为 80 V),额定电流 150 mA,适用于对中高频干扰进行抑制的空间受限电路。

二、主要电气参数

  • 通道数:2
  • 共模电感:100 µH @ 100 kHz
  • 额定电流:150 mA
  • 阻抗:5.1 kΩ @ 10 MHz(对共模噪声具有较高抑制能力)
  • 额定电压 / 耐压:80 V(DC/AC 均同)
  • 直流电阻(DCR):1.5 Ω
  • 工作温度范围:-25 ℃ ~ +105 ℃
  • 绝缘电阻:≥ 10 MΩ

(注:电感、阻抗为典型测试条件下的测量值,实际电路中会随频率、温度及电流有所变化。)

三、产品特性与优势

  • 高共模阻抗:在 10 MHz 时 5.1 kΩ 的共模阻抗可有效衰减射频与开关噪声,改善 EMI 性能。
  • 紧凑封装:3.2 × 2.5 mm 的 SMD-4P 小体积设计,适合空间受限的移动设备、消费电子和通信终端。
  • 宽温度范围与可靠绝缘:-25~+105 ℃ 的工作范围和 ≥10 MΩ 的绝缘电阻,保证长期可靠性。
  • 适中功耗:在额定电流 150 mA 下,直流功耗约为 I^2·R = 0.15^2 × 1.5 ≈ 0.034 W(约 34 mW),适合低功率应用场景。

四、典型应用场景

  • 数据接口和差分信号线的共模噪声抑制(例如 USB、HDMI、LVDS 等需要低干扰的高速信号)
  • 电源线前端滤波与开关电源的 EMI 抑制(低电流支路)
  • 工业控制与通信设备中对电磁干扰要求较高的模块隔离与滤波
  • 消费电子和便携设备的射频/EMI 抑制器件

五、封装与 PCB 布局建议

  • 器件靠近干扰源或连接器放置可获得最佳抑制效果(如靠近电源输入或信号接口处)。
  • 走线应尽量短且对称,以减少寄生电感与辐射。
  • 为保证散热与焊接质量,建议按厂家推荐的焊盘尺寸及回流焊工艺参数进行装配。
  • 高温环境或持续高电流场合应考虑额定值降额使用,避免长期超出额定温度或电流。

六、使用注意事项

  • 不要超过额定电压 80 V 与额定电流 150 mA,以免导致绝缘击穿或温升异常。
  • 测量时注意测试频率(本器件电感标注基于 100 kHz,阻抗基于 10 MHz),实际滤波特性需结合系统频谱评估。
  • 在高湿或腐蚀环境下应注意额外保护,以维持绝缘电阻与长期可靠性。

总结:PSCIAQ3225-101Z 是一款针对中高频共模干扰设计的、小体积、高阻抗的 SMD 共模滤波器,适合对 EMI 要求严格且空间受限的低/中功率电子系统。根据具体应用频谱与电流要求,合理布局与降额使用可以获得稳定的滤波效果与长期可靠性。

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
