PROD谱罗德PDMCAT221413-202MLB 共模滤波器产品概述

一、产品定位与典型应用场景

PROD谱罗德PDMCAT221413-202MLB是一款中大功率插件式共模滤波器,核心作用是抑制电路中的共模干扰(如电网波动、开关器件噪声),帮助设备满足EMC电磁兼容标准。其参数设计精准匹配多类工业及新能源场景,典型应用包括:

  1. 开关电源/电源适配器:200W-500W中功率电源的输入滤波,抑制电网传入的低频共模噪声,同时减少电源内部开关干扰向外辐射;
  2. 光伏逆变器/储能系统:光伏组件与电网之间的共模隔离,解决逆变器开关带来的高频噪声问题,提升系统效率与可靠性;
  3. 工业UPS/通信电源:机房UPS输入输出滤波,宽温范围适配-25℃(户外低温)至105℃(电源内部高温),满足7×24小时连续运行;
  4. 新能源汽车辅助电源:车载DC-DC转换器输入滤波,1.5kV AC耐压符合车载安规,14A电流覆盖辅助系统负载。

二、核心性能参数深度解析

该产品围绕“中大功率滤波+高可靠性”需求设计,关键指标具备明确的应用指向性:

1. 电感特性:2mH@1kHz

共模电感的电感量是干扰抑制的核心,2mH@1kHz覆盖1kHz-1MHz中低频段(共模干扰高发区)。相比小电感产品,2mH可有效衰减电网50/60Hz波动带来的低频共模噪声,且1kHz测试频率下电感值稳定,避免高频饱和。

2. 电流容量:14A额定电流

14A持续额定电流是核心优势,适配中大功率负载。实际应用中,负载电流≤14A时无磁饱和,滤波性能稳定;短期过载(如启动瞬间)可通过磁芯裕量避免性能突变,无需额外降额设计。

3. 安规与绝缘:1.5kV AC/3s耐电压

1.5kV AC耐压测试(持续3秒) 符合IEC 60950等安规标准,确保高电压环境下绝缘可靠,避免共模高压击穿绝缘层,降低短路风险,适合电网侧或高压输入场景。

4. 损耗与效率:15mΩ直流电阻(DCR)

15mΩ低DCR 大幅减少热损耗:满载14A时,损耗仅为 ( I^2R = 14^2 \times 0.015 = 2.94W ),发热远低于同类产品。低损耗不仅提升设备效率,还延长产品寿命,适应长时间连续工作。

5. 温度适应性:-25℃~+105℃

宽温范围 覆盖工业及户外极端环境:-25℃适配北方冬季户外设备,+105℃承受电源内部高温(如开关器件热辐射),无需额外散热,降低系统成本。

三、封装与可靠性设计特点

1. 插件式小尺寸封装

采用28mm×18.5mm插件封装,在保证性能的前提下节省PCB空间,适配紧凑型设备(如车载电源)。插件引脚焊接可靠性高于贴片,适合批量生产中的人工/自动焊接,减少虚焊风险。

2. 磁芯与绕组工艺

  • 磁芯:高磁导率铁氧体,配合对称双绕组工艺,保证共模电感对称性(减少差模干扰串扰);
  • 绕组:多股漆包线,降低高频集肤效应损耗,提升宽频滤波性能。

3. 绝缘与防护

绕组与磁芯间采用耐高温绝缘材料包裹,通过1.5kV AC耐压测试;引脚镀锡处理,提升焊接附着力与抗氧化能力,适应潮湿/盐雾环境(需配合防护)。

四、应用价值总结

该产品针对中大功率设备的共模滤波痛点,实现性能与成本的平衡:

  • 14A电流+2mH电感:无需并联小电流电感,简化电路设计;
  • 1.5kV耐压+宽温:满足工业/新能源场景的安规与环境要求;
  • 15mΩ低DCR:减少热损耗,提升系统效率与可靠性;
  • 小尺寸插件:适配紧凑型设备,降低生产难度。

产品已通过传导发射等EMC测试,可帮助设备快速通过CE、FCC认证,是工业电源、光伏逆变器、通信设备等领域的高性价比解决方案。

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
