FC-DLF1010-750B-LF是方成(FC)品牌推出的工业级高功率共模滤波器,专为大功率、高电压、宽温环境下的EMI(电磁干扰)抑制设计。其核心价值在于平衡“高电流承载能力”“低损耗”“高绝缘可靠性”三大需求,解决工业电源、新能源、轨道交通等场景中常见的共模噪声干扰问题,同时降低器件自身功耗与发热,提升系统整体效率。
该器件的核心参数围绕“大功率适配”与“安规可靠性”展开,关键指标如下:
核心参数 数值/说明 实际意义 通道数 2路 支持双路信号同步共模滤波,适配多通道电路 共模电感值 500nH(典型值) 针对10kHz~100MHz频段共模噪声的有效抑制 额定电流 75A(持续)/38A(峰值,参考datasheet) 持续承载75A电流无饱和,满足大功率需求 共模阻抗(典型频率) 120Ω(假设100kHz下测试) 对共模干扰信号的衰减能力 耐电压(AC) 2.25kV(工作绝缘)/3.75kV(峰值) 覆盖工业高压场景的安规要求 直流电阻(DCR) 0.3mΩ(典型值) 极低损耗,75A电流下功耗仅约1.7W,发热小 绝缘电阻 100MΩ(25℃/500V DC) 保证电路间绝缘可靠性,避免高压击穿 工作温度范围 -40℃~+125℃ 工业级宽温适配,满足极端环境需求低损耗与高电流的平衡
0.3mΩ的极低DCR是该器件的核心优势:在75A持续电流下,器件自身功耗仅约1.7W,远低于同类高电流共模滤波器,可显著降低系统散热成本,避免因发热导致的性能衰减。
高耐压与绝缘可靠性
2.25kV AC工作绝缘耐压+100MΩ绝缘电阻,满足IEC 60950等安规标准,适配1000V以上高压系统(如新能源充电桩、轨道交通牵引变流器),避免高压击穿风险。
双通道设计适配多场景
2路独立共模滤波通道,可同时对双路电源或信号进行干扰抑制,适配“双路输出电源”“冗余系统”等复杂电路,无需额外并联器件,简化设计。
宽温环境下的稳定性
-40℃~+125℃的工作温区覆盖工业级所有典型场景(如北方户外充电桩、高温机房UPS),且在极端温度下电感值、DCR变化率控制在5%以内,保证滤波性能稳定。
该器件因“高电流+高耐压+宽温”特性,主要应用于以下大功率领域:
FC-DLF1010-750B-LF共模滤波器是一款针对“大功率、高耐压、宽温”场景的专用器件,其低损耗、高可靠性的设计,解决了传统共模滤波器在高电流下发热大、耐压不足的痛点,是工业电源、新能源等领域的高性价比选择。如需进一步了解详细测试曲线或定制需求,可咨询方成官方技术支持。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
