PDUUAT105-202MLN 产品概述

一、产品简介

PDUUAT105-202MLN 是谱罗德(PROD)出品的一款高压共模滤波器(插件式),专为需要高绝缘耐压与较大直流载流能力的电源与信号线 EMI 抑制场合设计。器件体积紧凑(19.5×18×23 mm),便于通过孔插件安装,适用于工业电力电子、逆变器、电源滤波以及其他对共模干扰抑制有较高要求的系统。

二、主要规格参数

  • 型号:PDUUAT105-202MLN
  • 品牌:PROD(谱罗德)
  • 类型:共模滤波器(共模电感)
  • 共模电感:2 mH @ 1 kHz(标准测量条件:两线同相激励)
  • 额定电流:5 A(直流/有效值)
  • 额定电压(绝缘/工频耐压):1 kV AC(耐电压测试:1 kV AC,持续 3 s)
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 直流电阻(DCR):65 mΩ
  • 绝缘电阻:≥ 100 MΩ
  • 封装:插件(Through-hole)
  • 外形尺寸:19.5 × 18 × 23 mm

三、产品特点

  • 高耐压设计:可承受 1 kV AC 耐压(3 s),适合高压隔离与高压线路的共模噪声抑制。
  • 大电流容量:额定电流 5 A,可应用于中等功率电源回路。
  • 低 DCR:65 mΩ 的直流电阻有利于降低导通损耗,但在满载下仍需考虑热耗散。
  • 宽温度范围:-40 ℃ ~ +105 ℃,满足苛刻环境下的长期可靠性需求。
  • 紧凑插件封装:便于传统 PCB 插装和维修替换,适合量产装配工艺。

四、典型应用场景

  • 工业变频器与驱动器的 EMI 抑制与输入滤波。
  • 开关电源(SMPS)与高压电源线路的共模噪声抑制。
  • 逆变器、太阳能并网设备、高压直流供电系统的干扰抑制。
  • 对绝缘电压与耐压要求较高的控制与测量电路中,用于提升系统抗干扰能力。

五、安装与使用建议

  • 安装方式:插件(通孔)焊接至 PCB,建议在焊接区周围保留足够散热与绝缘距离。
  • 走线建议:将共模滤波器放置于噪声源(如开关器件)与受敏感电路之间,尽量减小输入端与输出端的环路面积以提高抑制效果。
  • 定位与固定:在高振动环境中推荐使用额外机械固定,避免焊点受力造成疲劳断裂。
  • 焊接工艺:遵循产品焊接温度与时间限制(参照厂商焊接建议),插件件应避免过长时间的高温暴露以保护绝缘性能。

六、热与电性能评估(设计注意事项)

  • 功率损耗计算:P = I^2 × DCR。以额定电流 5 A 计算,损耗约为 1.625 W(25 × 0.065 Ω),应评估 PCB 散热与周围器件的温升。
  • 饱和与降额:在高直流偏置或瞬态冲击电流下,磁芯可能出现饱和,导致共模抑制下降。建议对关键应用做实际电流-电感曲线验证,并在必要时进行电流降额或增加散热/通风措施。
  • 高压绝缘:耐压 1 kV AC(3 s)为耐压测试能力,不等同于连续工作电压,设计时应考虑工作环境的绝缘要求与安全间距。
  • 绝缘电阻:≥100 MΩ,表明良好绝缘特性,但在潮湿或污染环境中,应采取额外防护(涂覆或密封)。

七、订购信息与注意事项

  • 产品型号:PDUUAT105-202MLN,品牌:PROD(谱罗德)。
  • 选型时请确认:工作电流、实际频段(共模电感标称值为 1 kHz 条件下测得)、环境温度与耐压等级是否满足系统要求。
  • 质量与测试:在最终产品设计中建议进行实际系统级的 EMI 验证、温升测试与耐压/绝缘测试,以确保长期可靠性。
  • 若需更详细的电气特性曲线(如电感随电流的变化、频率响应曲线、热阻等)或认证资料,请联系供应商或索取器件数据表以便精确匹配设计需求。

PDUUAT105-202MLN 以其高耐压、适中电流能力与紧凑插件封装,适合需要在受限空间内实现高可靠 EMI 抑制的电源与工业应用。选型与布局时建议结合实际工作电流、频率成分及散热条件进行综合评估。

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
