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。
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。
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)。
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。
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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
