PDSQAT1918-103MLB 产品概述

一、产品简介

PDSQAT1918-103MLB 为谱罗德(PROD)出品的共模滤波器(共模电感),针对双线共模干扰抑制设计。器件在1 kHz 条件下表现为 10 mH 的共模电感量,适用于需要强力低频共模抑制的电源和信号链路,兼顾较大电流承载能力与较低的直流损耗。

二、主要性能与规格

  • 通道数:2(双线共模)
  • 电感量:10 mH @ 1 kHz(共模)
  • 额定电流:5 A(持续)
  • 直流电阻(DCR):50 mΩ
  • 耐电压:1 kV(耐压)
  • 绝缘电阻:≥100 MΩ
  • 工作温度范围:-40 ℃ ~ +105 ℃
  • 封装形式:插件(Through-Hole)
  • 尺寸:24 × 14.5 mm

三、结构与封装说明

该器件为插件式结构,便于手工或波峰/回流焊后插装的PCB组装方式。紧凑的 24×14.5 mm 尺寸适配多数中小型电源滤波区,线圈采用对称双绕组结构以实现优秀的共模抑制而尽量降低差模耦合。

四、主要特点与优势

  • 低频高感量:10 mH@1 kHz 对工频及低频干扰有显著抑制效果,适合开关电源、变频器等场景的低频噪声治理。
  • 大电流能力:5 A 额定电流满足中等功率电源和接口的通流需求。
  • 低 DCR 损耗:50 mΩ 的直流电阻有助于减少额外的功耗与发热,提升系统效率。
  • 高耐压与高绝缘:1 kV 耐压和 ≥100 MΩ 绝缘电阻保证长期可靠性与安全性。
  • 宽温工作范围:-40 ℃ 至 +105 ℃ 适用于工业级环境。

五、典型应用

  • 开关电源(SMPS)输入/输出共模干扰滤除
  • DC-DC 转换模块的 EMI 抑制
  • 电机驱动与变频设备的低频噪声治理
  • 工业控制、电力电子和通信电源线路的共模滤波

六、安装与使用注意事项

  • PCB 布局时尽量将该器件靠近干扰源或接口处,配合差模电容形成完整滤波网络。
  • 考虑到额定电流与散热,保持周围通风或合理散热路径以避免长期过热。
  • 插件焊接时建议按照厂家推荐的温度曲线与焊接工艺,避免超温影响绝缘与线圈特性。
  • 若应用在高压或敏感场合,须进行耐压与绝缘测试确认。

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
