SMCM1211-102T是顺翔诺(SXN)推出的双通道表面贴装(SMD)共模滤波器,专为中功率电路的高频共模噪声抑制设计。其核心价值是在不衰减差模信号(如电源电流、有效数据)的前提下,精准衰减线路中的共模干扰,解决电磁兼容(EMC)问题;同时兼顾小型化、低损耗与宽温可靠性,适配多类电子设备的滤波需求。
该产品的参数设计精准匹配中高频干扰场景与中功率承载需求,核心优势体现在以下维度:
额定电流6A、额定电压125V,可稳定支撑中功率直流/交流电路(如小型开关电源、车载电源模块)的滤波需求。实际应用需注意:高温环境下(如125℃)需按厂家降额曲线适当降低工作电流(建议≤4.8A),确保长期可靠性。
阻抗特性为1kΩ@100MHz——100MHz是开关电源(LLC、Flyback拓扑)、高速数字电路(DDR4/DDR5、千兆以太网)的典型干扰频点,该阻抗值可有效衰减共模噪声,帮助设备快速通过CE、FCC等EMC认证。
直流电阻(DCR)仅14mΩ,通态损耗极低(6A工作时损耗约0.5W),可减少发热、提升电路效率,尤其适合对功耗敏感的便携设备(如笔记本充电器、无人机电源)。
工作温度范围为**-40℃~+125℃**,覆盖工业控制、汽车电子等严苛环境(如户外PLC、车载中控);绝缘电阻≥10MΩ,确保输入输出端电气隔离,避免短路风险,提升电路安全。
单颗集成2通道滤波,无需多颗并联即可实现双路滤波,节省PCB空间约30%,适配高密度设计场景(如服务器主板、小型通信模块)。
SMCM1211-102T采用SMD 12×10.8mm小型化贴片封装,具备以下工艺优势:
结合参数特性,该产品广泛应用于以下领域:
为确保性能稳定,应用时需注意:
SMCM1211-102T通过平衡滤波性能、功率承载与小型化设计,成为中功率电路EMC优化的高性价比选择,可覆盖多类电子设备的滤波需求。

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.
