PDSQAT1212-203MLB 共模滤波器产品概述

PDSQAT1212-203MLB是PROD谱罗德品牌推出的插件式低频共模滤波器,专为电源回路的电磁干扰(EMI)抑制设计,整合了稳定电感量、低损耗、宽温适应性等核心特性,适配中小功率电子设备的滤波需求,兼顾可靠性与成本效益。

一、产品定位与核心属性

该产品属于共模滤波器范畴,通过双线并绕磁芯的结构设计,实现对共模噪声的高阻抗抑制(对差模电流低阻抗),主要解决电路中因电磁辐射、传导干扰导致的性能不稳定问题。其定位为低频段(1kHz测试范围)中小功率场景的滤波解决方案,适合无需贴装工艺的传统PCB布局。

二、关键电气性能参数详解

1. 电感量与频率适配

标称电感量为20mH@1kHz,测试频率对应工频(50/60Hz)及其谐波的典型干扰范围,稳定的电感值确保对低频共模噪声的有效抑制。共模电感的工作原理是:当共模电流通过双线绕组时,磁芯中产生同向磁通,磁导率提升,形成高阻抗;差模电流则产生反向磁通,磁芯饱和抑制,阻抗极低,从而实现噪声分离。

2. 电流承载与损耗控制

  • 额定电流2A:满足10W-50W中小功率电源的连续工作需求(如手机适配器、小型开关电源);
  • 直流电阻(DCR)180mΩ:显著降低电流损耗(连续工作损耗仅0.72W,P=I²R),减少发热,提升产品寿命与电路效率。

3. 电气安全与绝缘性能

  • 耐电压1kV:可承受短时间过电压冲击(如电网浪涌),避免击穿损坏;
  • 绝缘电阻≥100MΩ(DC500V/1min测试):确保线-地、线-线之间的绝缘可靠性,符合电气安全规范。

三、结构设计与封装特性

  • 插件封装:引脚设计便于手工或自动焊接,无需专用贴装设备,降低生产门槛;
  • 紧凑体积:18×18×11mm(长×宽×高),适配PCB板的布局优化,适合空间受限的设备;
  • 磁芯与绕组:采用锰锌铁氧体磁芯(适合低频应用),双线并绕工艺保证电感量稳定,减少磁芯损耗。

四、环境适应性与可靠性

  • 宽温范围:工作温度覆盖**-40℃+105℃**,满足工业级(-40+85℃)与高温场景(如靠近热源的设备)需求;
  • 稳定性能:极端温度下绝缘电阻无明显衰减,电气参数保持稳定;
  • 可靠性验证:经过老化测试与EMI性能验证,符合CE、FCC等电磁兼容标准。

五、典型应用场景

  1. 开关电源滤波:AC-DC/DC-DC电源输入/输出端,抑制共模噪声,助力产品通过EMC认证;
  2. 适配器与充电器:手机、笔记本电脑等设备的电源适配器,过滤工频干扰与开关噪声;
  3. 工业控制设备:PLC、传感器等工业设备的电源回路,抑制现场电磁干扰;
  4. 小型家电与仪器:电视机、示波器等,减少干扰对信号的影响,提升显示/测量精度。

六、选型优势总结

对比同类插件共模滤波器,PDSQAT1212-203MLB的核心优势在于:
① 20mH@1kHz电感量与2A电流的平衡,适配中小功率低频需求;
② 低DCR(180mΩ)降低损耗,提升效率;
③ 1kV耐电压与宽温范围,增强环境适应性;
④ 紧凑插件封装,便于焊接与布局。

该产品是替代进口同类产品的高性价比选择,适合对成本敏感、无需贴装工艺的批量应用场景。

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
