PCAQ1211MW-801 产品概述

一、产品简介

PCAQ1211MW-801 是谱罗德(PROD)推出的一款双通道共模滤波器,采用 SMD-4P 封装(12 × 10.8 mm),面向对差模干扰要求不高但对共模抑制能力有较高要求的电源与信号线滤波场景。器件额定电流 8A,额定电压 125V(AC/DC),设计用于抑制高频共模干扰,改善系统电磁兼容性(EMC)。

二、主要电气参数

  • 通道数:2
  • 额定电流:8 A
  • 额定电压:125 V(AC)/125 V(耐电压)
  • 阻抗:800 Ω @ 100 MHz(共模)
  • 直流电阻(DCR):8 mΩ
  • 绝缘电阻:≥ 10 MΩ
  • 工作温度:-25 ℃ ~ +125 ℃

三、功能与性能特点

  • 优异的高频共模抑制:在 100 MHz 附近达到约 800 Ω 共模阻抗,有效抑制开关电源、DC-DC 与数字电路产生的共模噪声。
  • 低直流损耗:8 mΩ 的 DCR 有利于高电流路径中的能量效率,但在 8 A 工作时仍需关注 I^2R 发热(最大理论损耗约 0.512 W)。
  • 适应宽温域:-25 ℃ 至 +125 ℃ 的储运与工作温度范围,适用于一般消费、工业及部分严苛环境应用。
  • SMT 封装:表面贴装形式利于自动化生产与小型化设计。

四、典型应用场景

  • 开关电源输出/输入滤波(AC/DC 小功率模块)
  • USB、HDMI、LAN 等接口的共模干扰抑制(当电压等级与电流允许时)
  • 工业控制、通信设备、家电的输入电源滤波与EMC整改
  • 电机驱动与电源线滤波(须评估发热与耐压)

五、选型与使用建议

  • 热管理:在 8 A 持续工作条件下需评估器件温升与周围散热条件,必要时留足铜箔面积或加散热通道。
  • 布局:滤波器应靠近干扰源或接口放置,走线尽量对称、短且靠近滤波器输入/输出端,减小差模串联电感。
  • 耐压与绝缘:器件耐压 125 V,不能替代高压隔离组件,电路设计时注意绝缘与爬电距离。
  • 焊接工艺:遵循厂家推荐的回流温度曲线,避免过高温度和重复冷热冲击影响可靠性。

六、可靠性与检验建议

  • 建议进行高压(Hi-Pot)测试、绝缘电阻测试、阻抗频谱验证及焊接可靠性(热循环、盐雾可按需求)。
  • 在大电流应用场合进行实际功耗与温升测量,验证长期稳定性。

PCAQ1211MW-801 适合需要在中低电压、较高电流条件下提升共模抑制的应用,通过合理布局和热设计,可在多类消费与工业电子设备中发挥良好 EMC 改善效果。若需完整数据手册或应用评估,可联系供应商索取详细资料与测试报告。

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
