LCM7060-701是FC方成品牌推出的SMD型双通道共模滤波器,针对中低功率电路的共模干扰抑制需求设计,具备高共模阻抗、低直流损耗、宽电压耐受等核心优势,广泛适用于消费电子、车载电子、小型电源等场景的EMC防护。
共模滤波器的核心作用是衰减线路中的共模噪声(即两条导线同时携带的同相位干扰信号),而对差模信号(如电源电流、差分数据)的传输影响极小。LCM7060-701采用双通道设计,可同时适配双导线系统(如电源L/N线、USB差分线、以太网双绞线等),在不影响正常信号传输的前提下,有效抑制100MHz附近的高频共模干扰,帮助产品满足CE、FCC等EMC认证要求。
产品核心参数为700Ω@100MHz(共模阻抗),100MHz是电子设备EMI的关键频段(如开关电源的高频纹波、无线通信的邻频干扰),该阻抗值表明:在100MHz频率下,滤波器对共模噪声的衰减能力较强,可有效降低噪声向空间辐射或通过导线传导的风险。
直流电阻(DCR)仅10mΩ,是该产品的核心优势之一:当线路传输4A直流电流时,压降仅为0.04V(V=I×R),功率损耗仅0.16W(P=I²×R),几乎不影响电源效率或信号完整性,适合对直流损耗敏感的电池供电设备(如笔记本电脑、便携式仪器)。
绝缘电阻≥10MΩ,满足基本电气绝缘要求,可防止共模干扰通过滤波器耦合到其他线路,同时避免元件内部短路风险;产品符合常规安全规范,可在-40℃~+85℃的温度范围内稳定工作(常规SMD元件的温度适应性)。
LCM7060-701采用表面贴装(SMD)封装,具备以下优势:
FC方成是国内专注于EMC元件研发的品牌,LCM7060-701经过多项可靠性测试:
LCM7060-701以高性价比、低损耗、易安装的特点,成为中低功率电路EMC防护的优选元件,可有效解决电子设备的共模干扰问题,提升产品的电磁兼容性。
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.
