PDUUAT98-203MLN 共模滤波器 — 产品概述

一、产品简介

PDUUAT98-203MLN 为 PROD(谱罗德)系列高耐压共模滤波器,采用插件封装(4P,尺寸 17×12mm),针对对地或线间干扰抑制设计。器件在 1kV 交流耐压条件下经 3 秒耐受测试,适用于需要高绝缘和低频共模干扰抑制的场合。

二、主要电气参数

  • 共模电感:20 mH @ 1 kHz(两通道共模抑制性能优异)
  • 额定电流:600 mA(连续工作电流上限)
  • 直流电阻 (DCR):1.2 Ω(每通道典型值)
  • 额定电压:1 kV(标注绝缘与耐压等级)
  • 绝缘电阻:≥100 MΩ
  • 耐电压测试:1 kV AC,3 秒
  • 工作温度范围:-40 ℃ 至 +105 ℃

三、结构与封装

本器件为插件式四引脚(4P)封装,物理尺寸 17×12 mm,便于通过孔安装和手工或波峰焊装配。两通道设计常用于双线信号或电源差分线的共模抑制,节省板面同时提高可靠性。

四、典型应用场景

  • 工业与仪表设备的信号线/控制线 EMI 抑制
  • 通信接口、传感器接口的共模噪声过滤
  • 需要高绝缘电压的系统隔离、耐压测试环境
  • 小功率开关电源输入端到地的低频干扰抑制

五、设计与使用建议

  • 电流选型:连续电流不应超过 600 mA,考虑浪涌和温升应适当留有裕量。
  • 温度与散热:器件工作温度上限 +105 ℃,长期在高温环境下需评估寿命与电感衰减。
  • 与电容配合:在 EMI 抑制中可与差分(X)或到地(Y)电容构成 π 型滤波网络,但注意安全规范与漏电流要求。
  • 焊接注意:插件安装时遵守常规焊接工艺,避免超过推荐回流或波峰温度对绝缘材料的影响。
  • 绝缘与安全:尽管耐压 1 kV,实际用于安全类产品时应参考相关安全标准并做完整认证。

六、可靠性与测试

PDUUAT98-203MLN 通过 1 kV AC、3 秒耐压测试并具备 ≥100 MΩ 绝缘电阻,保证在高压隔离条件下的可靠性。定期检查直流电阻和电感特性可发现老化或损伤问题。

七、总结

PDUUAT98-203MLN 为一款专注于低频共模干扰抑制且具备高耐压能力的插件式滤波器,适合对绝缘与 EMI 要求较高的工控、通信和小功率电源应用。选型时需关注额定电流、温升和系统安全规范,结合电容与接地策略获得最佳滤波效果。若需样品或详细数据手册,可联系 PROD 或其授权分销商获取完整规格与测试曲线。

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
