PDMCAT221413-502MLB 产品概述

一、产品简介

PDMCAT221413-502MLB 为谱罗德(PROD)推出的一款高压共模滤波器(共模电感),适用于高电压、大电流场合的干扰抑制与共模噪声过滤。该器件为插件(Through‑Hole)封装,四引脚布局,外形尺寸约 28 × 18.5 mm,结构紧凑、耐压性能突出,适合AC/DC电源前端、逆变器与工业电源等应用。

二、主要参数

  • 通道数:2(共模)
  • 公称电感:5 mH @ 1 kHz(共模)
  • 额定电流:9.5 A
  • 额定电压(耐压):1.5 kV AC(耐压测试 1.5 kV AC,3 秒)
  • 直流电阻 DCR:28 mΩ
  • 工作温度范围:-25 ℃ ~ +105 ℃
  • 封装:插件-4P;尺寸:28 × 18.5 mm
  • 品牌:PROD(谱罗德)

三、性能与特点

  • 高阻隔电压:1.5 kV AC 的耐压能力适合高压隔离场合,能有效保证线间/对地绝缘强度。
  • 大电感量:5 mH@1 kHz,在低频到中频段对共模噪声有良好抑制作用。
  • 高电流承载:9.5 A 额定电流支持较大负载,但在接近额定电流时需关注发热与功耗。根据 DCR 28 mΩ,满载功耗约 P = I^2·R ≈ 9.5^2·0.028 ≈ 2.53 W,需考虑散热与可能的电流降额。
  • 宽温度范围:-25~+105 ℃,适合多数工业环境。
  • 通过孔插件形式便于波峰/回流焊前后加工与手工装配。

四、典型应用

  • 开关电源(SMPS)输入端共模干扰抑制
  • 逆变器、变频器和电机驱动系统的EMI滤波
  • 工业电源与配电设备的共模噪声控制
  • 高压电源与充电桩等需要高绝缘等级的场合

五、安装与使用注意事项

  • 热管理:若长期接近额定电流使用,应保证良好散热或对电流进行适当降额,以避免绕组过热和磁芯饱和。
  • PCB 布局:保持器件与敏感信号间的合理间距,确保绝缘爬电距离满足系统工作电压要求;共模滤波器输入与机箱接地应合理安排以避免形成地环路。
  • 焊接工艺:插件件可采用波峰焊或手工焊接,注意焊接温度与时间不要超过器件耐受范围以免内部绝缘或结构损伤。
  • 耐压测试:出厂耐压为 1.5 kV AC/3s,系统级试验时应按标准逐步施加电压并记录泄漏电流,避免重复高压冲击导致老化。

六、选型建议与可靠性

  • 若系统工作频率远高于 1 kHz,应确认器件在目标频段的阻抗特性及其对相应频率的衰减效果。
  • 对于连续高电流或高温环境,建议留有安全余量(例如 70%~80% 额定电流)并做热仿真或实测温升。
  • 如需医疗、铁路或汽车等特殊认证应用,请向供应商确认相应认证与寿命数据。
  • 建议在样机阶段进行实际系统级 EMI 测试、温升及老化评估,以验证在目标工况下的长期可靠性。

总结:PDMCAT221413-502MLB 以其高耐压、大电感与较高电流承载能力,适合工业与电力电子领域的共模噪声抑制需求;在使用中需重视热管理与绝缘布局,以保证长期稳定可靠运行。

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
