PSEFCI5025-251共模滤波器产品概述

PSEFCI5025-251是谱罗德(PROD)推出的一款SMD封装共模滤波器,专为抑制电子设备中的共模电磁干扰(EMI)设计,兼具高电流承载能力、小体积、宽温适应等核心优势,可满足工业控制、汽车电子、消费电子等多领域的EMI整改需求。

一、产品定位与核心作用

共模滤波器的核心功能是过滤电路中的共模干扰信号,同时保留差模信号(如电源电流、数据信号)的正常传输,避免干扰影响设备性能或违反电磁兼容(EMC)标准。PSEFCI5025-251针对中高电流场景优化,主打“小体积+高可靠性”,适合需要紧凑设计且对EMI抑制有明确要求的电子设备。

二、关键性能参数深度解析

(1)电流与电压能力

  • 额定电流5A:可稳定承载5A直流/交流电流,覆盖多数电源线路(如12V/24V电源、功率模块输入输出)的电流需求,无需额外并联滤波器,简化电路设计。
  • 额定电压125V:支持125V直流/交流电压输入,适配低压直流电源、车载12V系统、工业24V系统等场景;耐电压50V(注:此处为短时间耐受电压,需注意额定电压与耐电压的应用区别)。

(2)干扰抑制核心:阻抗特性

产品在100MHz频率下的共模阻抗为250Ω——100MHz是开关电源、高速数字电路(如MCU、FPGA)产生共模干扰的典型频段,较高的阻抗可有效衰减该频段内的干扰信号,帮助设备通过EMC认证(如FCC Part 15、CE EN 55032)。

(3)低功耗与可靠性:直流电阻(DCR)

直流电阻仅20mΩ,远低于同类高电流共模滤波器的平均水平。低DCR意味着电流通过时的功耗极低(5A下功耗仅0.5W),发热小,可长期稳定工作而无需额外散热设计,提升设备可靠性。

(4)环境适应:宽温范围与绝缘性能

  • 工作温度-25℃~+125℃:覆盖工业级(-20℃+85℃)和部分汽车级场景(-25℃+125℃),可在低温存储、高温运行的恶劣环境下正常工作。
  • 绝缘电阻10MΩ:满足基本绝缘要求,避免电路间短路或漏电,保障设备安全。

三、封装形式与典型应用场景

(1)超小SMD封装

产品采用4.8mm×5mm×2.5mm的SMD封装,体积紧凑,可直接贴装于PCB表面,适合高密度电路设计(如小型电源适配器、车载传感器模块),节省PCB空间,降低设备整体尺寸。

(2)典型应用场景

  • 工业控制领域:PLC、变频器、伺服驱动器的输入输出滤波,抑制高频干扰对控制信号的影响;
  • 汽车电子领域:车载USB充电模块、仪表盘电源、传感器接口的EMI滤波,避免干扰车载CAN总线等通信系统;
  • 消费电子领域:电源适配器、机顶盒、路由器的AC/DC电源滤波,满足安规认证要求;
  • 通信设备领域:小型基站、无线模块的电源滤波,减少电磁干扰对信号传输的影响。

四、品牌与可靠性保障

谱罗德(PROD)是国内专注于电磁兼容元器件的专业厂商,PSEFCI5025-251经过高低温存储测试、温循测试、振动测试等可靠性验证,符合RoHS无铅环保要求,可稳定应用于各类工业与消费电子场景。

总结

PSEFCI5025-251共模滤波器以“小体积、高电流、宽温适应、低功耗”为核心优势,精准匹配多领域EMI抑制需求,是紧凑设计电子设备的优选EMC解决方案。其可靠的性能与谱罗德的专业支持,可帮助客户快速通过EMC认证,提升产品竞争力。

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
