PDUUAT98-501MLN 产品概述

一、产品简介

PDUUAT98-501MLN 为谱罗德(PROD)推出的高压共模滤波器(Common‑Mode Choke),属于插件式封装产品,外形尺寸 17 × 12 mm,4 针脚(4P)。该器件针对对称两线制信号/电源线的共模干扰抑制而设计,标称共模电感 500 μH(测量点:1 kHz),额定电流 4 A,额定电压 1 kV(AC),耐压性能为 1 kV AC,持续 3 秒,直流电阻(DCR)约 45 mΩ,工作温度范围 -40 ℃ 至 +105 ℃,绝缘电阻 ≥ 100 MΩ。

二、主要性能参数

  • 通道数:2(适用于两线共模抑制)
  • 共模电感:500 μH @ 1 kHz
  • 额定直流电流:4 A
  • 额定电压:1 kV(AC)
  • 耐压:1 kV AC,3 秒
  • 直流电阻(DCR):45 mΩ(典型值)
  • 工作温度:-40 ℃ ~ +105 ℃
  • 绝缘电阻:≥ 100 MΩ
  • 封装形式:插件(Through‑Hole),4P
  • 尺寸:17 mm × 12 mm
  • 品牌:PROD(谱罗德)

三、关键特性与优势

  • 高共模抑制:500 μH 的高感值在低频段(如工频与开关电源低频分量)具有明显的共模抑制效果,有助于降低系统电磁干扰(EMI)基频及其谐波。
  • 高压耐受:1 kV 的额定与耐压能力,适合需要高绝缘或高电压隔离的场合,增加系统安全裕量。
  • 低损耗:DCR 约 45 mΩ,意味着在额定电流下铜损相对较低,适合中等功率线路应用。
  • 宽温度范围:-40 ~ +105 ℃ 可适应工业级环境温度要求。
  • 插件封装:便于维修、更换及在较厚的绝缘板或连接端子上安装。

四、典型应用场景

  • 工业电源输入滤波(如变频器、伺服驱动器、工业开关电源)
  • 高压直流/交流系统的共模噪声抑制(如光伏逆变器、DC‑DC 高压侧)
  • 电池管理系统和电动工具输入滤波(在额定电流范围内)
  • 通信基站及信号接口的共模干扰控制(需高压隔离场合)
  • 需要高绝缘电压及良好共模抑制的测试与测量设备

五、使用建议与设计注意事项

  • 额定电流限制:在设计中应保证通过器件的连续电流不超过 4 A。若存在长时间高温或高环境温度,应考虑对额定电流进行适当降额。
  • 直流偏置影响:若在线路中存在较大直流偏置电流,可能导致磁芯饱和,从而降低共模电感值,应在选型和电路仿真时考虑 DC 偏置效应。
  • 布局与接地:共模扼流圈应成对串联放置在电源/信号输入端,确保两线对称布线;与后级滤波/接地电容配合使用(例如 Y 电容)可提高整体 EMI 抑制性能。插件安装需保证焊盘与走线对称、最小化差模回路面积。
  • 安全间距与爬电距离:器件标称 1 kV 电压等级,电路板设计时仍应按照目标应用的安全标准(如 IEC 系列)确定爬电/间隙距离,保持足够的绝缘及机械间隔。
  • 温升与散热:在接近额定电流工作时,注意器件温升;若长期满载工作,建议评估环境散热条件并预留热裕量。

六、可靠性与测试

  • 绝缘测试:出厂典型检验包含绝缘电阻及耐压测试,器件额定耐压为 1 kV AC,持续 3 秒,绝缘电阻 ≥ 100 MΩ,有利于高压绝缘可靠性。
  • 环境可靠性:适用于工业级温度循环及一般振动环境。实际应用时可依据系统要求进行额外的振动/冲击/温循环验证。
  • 寿命与老化:磁性元件长期工作可靠性与环境(温度、湿度、过流)相关。建议在关键应用中进行寿命评估或长期加速试验。

七、采购与替代考量

  • 选型时确认机械尺寸(17×12 mm)与安装孔位兼容 PCB 布局及面板要求。
  • 若需要更高电流或更低 DCR,可在同类产品中查找更大尺寸或不同绕组设计的型号;若需要更高耐压或符合特定安全标准,应与供应商确认认证情况。
  • 采购时建议取得样品并在目标系统中进行 EMI 测试与温升测试,验证实际抑制效果与热性能。

概括:PDUUAT98-501MLN 是一款面向工业与高压应用的高感共模滤波器,适合在需兼顾高压绝缘与共模噪声抑制的电源输入或信号接口中使用。合理的电流控制与布局、对直流偏置与温升的评估,是发挥其最佳性能的关键。若需更详细的波形响应或频率特性曲线,请向供应商索取完整的频率响应与测试报告。

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.
