PDUUAT98-102MLN 产品概述

一、产品概述

PDUUAT98-102MLN 为谱罗德(PROD)系列共模滤波器,采用插件四脚封装(4P),外形尺寸约 17×12 mm。该器件在 1 kHz 时提供 1 mH 的共模电感量,额定电流 3 A,额定耐压 1 kV(AC),耐压测试:1 kV AC,持续 3 秒。适用于需要高压绝缘与共模干扰抑制的电源与信号路径场合。

二、主要电气与环境参数

  • 共模电感:1 mH @ 1 kHz
  • 额定电流:3 A(连续)
  • 额定电压(AC):1 kV
  • 耐压能力:1 kV AC,3 秒
  • 直流电阻(DCR):90 mΩ
  • 绝缘电阻:100 MΩ
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 封装形式:插件(4 引脚),尺寸 17×12 mm

三、产品特点与优势

  • 高电感量:在低频(1 kHz)下提供 1 mH 共模抑制,适合窄带或低频干扰治理。
  • 高耐压绝缘:1 kV AC 耐压能力,满足高压隔离和安规前端需求。
  • 插件式封装:方便手工或波峰、回流辅助插件工艺,利于维修与快速装配。
  • 宽温范围:-40℃~+105℃,适应工业级环境。
  • 低直流电阻:90 mΩ 在额定电流下能量耗散可控,便于热设计。

四、典型应用场景

  • UPS、电源模块和逆变器的输入共模滤波。
  • 光伏并网逆变器、中高压开关电源的干扰抑制与隔离。
  • 需要高绝缘等级的测控与检测电路的共模干扰滤除。
  • 工业驱动与通信电源的EMI/EMC整改。

五、热与电流管理(实务建议)

  • 功耗估算:在 3 A 连续电流下,最大铜损 P = I^2 × DCR = 3^2 × 0.09 Ω ≈ 0.81 W,实际温升与散热条件、PCB 结构相关。
  • 散热建议:在温度较高或通流频繁的场合,建议留有导热铜箔和空气流通以降低结温。
  • 电流余量:为避免磁芯饱和与长期老化,建议持续工况下采用不高于额定电流 80% 的裕量;短时冲击电流需结合实际波形评估。

六、安装与测试注意事项

  • 安装方向:四脚插件按线路设计焊接,注意两侧线圈极性与 PCB 接地布局,以保证共模抑制效果。
  • 耐压测试:出厂耐压为 1 kV AC(3 s),现场测试时请参考相关安规和测试方法,做好充放电与旁路保护。
  • 测试判断:如需验证滤波效果,建议在目标频段使用网络分析仪或频谱仪测量差模/共模抑制曲线。
  • 储存与搬运:避免潮湿、高温及强磁场环境,存放温湿度应符合常规电子元件要求。

七、选型与采购建议

  • 若系统工作电压或耐压要求高于 1 kV,或有更严格的安规认证需求,请与供应商沟通定制或查看同系列更高耐压型号。
  • 订购时确认封装尺寸、引脚排列及电感标称频率(1 kHz)是否满足滤波目标;同时核对额定电流、DCR 与系统热预算匹配。
  • 品牌与技术支持:品牌 PROD(谱罗德),如需样品测试或技术数据表(包括频率响应曲线、温升曲线、尺寸图),请联系供应商获取详细资料。

总结:PDUUAT98-102MLN 以其 1 mH 共模电感、1 kV 耐压和插件小型化封装,为高绝缘需求下的共模干扰抑制提供可靠选择。合理的电流裕量与散热设计可显著提升长期稳定性和滤波性能。

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
