PDUUAT98-103MLN 产品概述

一、产品简介

PDUUAT98-103MLN 是 PROD(谱罗德)推出的一款高压共模滤波器(共模电感/共模扼流圈),为需要高压隔离与低频共模干扰抑制的电路提供解决方案。器件为插件式(4P),外形尺寸 17 × 12 mm,适用于板对板或面板安装的电源与信号线干扰治理场合。

二、主要技术参数

  • 共模电感量:10 mH @ 1 kHz(共模)
  • 直流电阻(DCR):700 mΩ
  • 额定电流:700 mA(连续)
  • 额定耐压 / 绝缘性能:1 kV(AC),耐压测试 1 kV AC,持续 3 秒
  • 绝缘电阻:100 MΩ
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 通道数:2(双通道)
  • 封装形式:插件(4 引脚),尺寸 17 × 12 mm

三、性能与特点

  • 高共模电感(10 mH@1 kHz),对低频至中低频段(如工频及其谐波、开关电源低频噪声)有良好的抑制效果。
  • 1 kV 耐压与 100 MΩ 绝缘电阻,适合高压系统中对绝缘与安全有要求的场景(需按具体系统标准进一步验证)。
  • 插件封装便于安装与更换,适合维修性要求较高的设备。
  • 双通道设计可用于差分线路或双回路的共模抑制,结构对称,有利于保持差模信号完整性。
  • DCR 为 700 mΩ,在额定电流下会产生一定的压降与热耗(参考功耗约 0.34 W),需在设计中考量散热与功耗预算。

四、典型应用场景

  • 高压直流/交流电源的输入滤波与干扰抑制
  • 工业电源、变频器前端共模噪声治理
  • 测量仪器与高压信号链路的共模干扰抑制
  • 高压隔离需求的电子设备中作为额外的共模滤波单元

五、安装与使用建议

  • 为保证长期可靠性,建议在额定电流条件下留有余量(常规建议工作电流不超过额定值的 70%~80%);若持续靠近额定值,应验证温升与寿命。
  • 设计 PCB 布局时注意保持器件两端的爬电距离与气隙,满足 1 kV 绝缘需求的系统规范。
  • 共模电感对直流偏置敏感,直流电流会降低交流电感值,设计时需考虑 DC 偏置对滤波性能的影响。
  • 与差模电容、X/Y 安全电容等配合使用可以构成更完整的 EMI 滤波网络,根据系统噪声频谱选择合适的补充元件。
  • 插件焊接与机械固定时避免过大机械应力,保证接触可靠并便于散热。

六、选型与注意事项

  • 在高压或有安全认证要求的产品中使用前,请按最终应用的法规与标准(如系统耐压、漏电流限制等)进行验证。
  • 对于对压降敏感的电路,应评估 700 mΩ DCR 带来的电压损耗与热量。
  • 若目标频段为高频 EMI(MHz 级),建议结合差模电感或其他高频器件共同设计滤波网络,以覆盖更宽的频谱。

总结:PDUUAT98-103MLN 以其高共模电感量、1 kV 耐压和插件化封装,适合需要高压隔离与低频共模干扰抑制的工业与电源应用。选用时需关注直流压降、温升与系统绝缘要求,配合合适的布线和补偿元件,可在多种高压场景中发挥良好效果。

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
