LCM9070-701是方成(FC)品牌推出的双路表面贴装(SMD)共模滤波器,针对电子设备中高频共模噪声干扰问题设计,尤其适配中等功率(≤6A)、低压直流(≤80V) 的电源/信号回路。其核心价值在于:通过100MHz频段700Ω的精准阻抗特性高效抑制高频干扰,同时以10mΩ低直流电阻保障回路效率,是满足EMC电磁兼容认证、提升设备信号稳定性的实用型器件。
双路设计支持双极性电源(如±12V) 或双输出回路(如24V双支路),无需额外并联器件即可覆盖多回路干扰抑制需求,简化PCB布局,降低设计复杂度。
满足小型开关电源、LED驱动、工业控制模块等中等功率负载的持续电流需求,避免因电流过载导致滤波性能下降或器件损坏,适配多数消费/工业场景的功率范围。
100MHz是开关电源、通信设备等高频噪声的高发频段(如开关管高频振荡、无线信号干扰),700Ω的高阻抗可有效衰减该频段共模干扰,帮助设备通过CE、FCC等EMC认证。
覆盖12V、24V、48V等常用低压直流系统,适配消费电子(手机快充)、工业自动化(PLC)、通信设备(路由器)等多数场景的电压范围,无需额外降压/升压适配。
低电阻设计使6A电流下的压降仅为0.06V,功率损耗仅0.36W,显著降低器件发热,提升电源回路效率——尤其适合对能耗敏感的便携设备(如笔记本电源)或长时间运行的工业模块。
保障通道间及对地的绝缘可靠性,防止短路故障,满足工业级环境的绝缘要求(如车间高湿度、粉尘场景),提升设备运行安全性。
LCM9070-701采用7×9mm SMD贴片封装,具备以下适配优势:
如手机快充、笔记本电源、LED驱动电源:需抑制开关管产生的100MHz左右高频共模噪声,6A电流满足多LED串或快充输出需求,低DCR减少电源损耗。
PLC输入输出模块、传感器信号调理电路:80V电压适配工业48V直流系统,双路设计支持双信号通道,抑制现场电机、变频器产生的电磁干扰。
以太网交换机、路由器的电源回路:过滤共模干扰保障数据传输稳定性,小尺寸封装适配设备高密度PCB布局。
智能音箱、机顶盒的电源模块:抑制内部开关电源噪声,避免对WiFi、蓝牙等无线信号的干扰,提升用户体验。
对比同类6A级SMD共模滤波器,LCM9070-701的核心优势在于:
综上,LCM9070-701是一款“高性价比、性能均衡、适配性强”的共模滤波器,适合对EMC、功率效率、空间布局有要求的电子设备设计。

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.
