SMCM1211-701T 共模滤波器产品概述

一、产品定位与核心价值

SMCM1211-701T是顺翔诺(SXN)推出的贴片式(SMD)共模滤波器,专为抑制电路中共模电磁干扰(EMI)设计,同时兼顾中功率承载能力与紧凑体积。其核心价值在于:在12×10.8mm的小封装内,实现8A额定电流、700Ω干扰抑制阻抗,适配高密度PCB布局需求,平衡了性能、体积与成本,适用于消费电子、工业控制等多领域的电源/信号滤波场景。

二、关键参数明细

SMCM1211-701T的参数围绕“低损耗、宽温域、中功率”设计,核心参数如下:

  1. 电气核心参数:
    • 通道数:2通道(双路共模滤波,覆盖双路电路干扰抑制)
    • 额定电流:8A(持续工作电流,满足多数中功率电路需求,如12V/5A适配器)
    • 额定电压/耐电压:125V AC/DC(符合低压电路安全标准,适配多数直流/交流电源)
    • 阻抗(@指定频率):700Ω(针对MHz级共模干扰频段的抑制能力,提升EMC兼容性)
    • 直流电阻(DCR):6mΩ(低电阻设计,减少功率损耗,降低发热)
  2. 可靠性参数:
    • 工作温度范围:-40℃~+125℃(工业级宽温,适应极端环境)
    • 绝缘电阻:≥10MΩ(25℃、500V DC条件下,保障电气隔离安全)

三、封装与物理特性

SMCM1211-701T采用SMD贴片封装,尺寸为12mm×10.8mm×(行业常规高度约5mm),适配标准贴片贴装工艺,无需额外插件空间。其紧凑体积可直接集成于高密度PCB(如电源适配器、小型工业控制器),不影响设备小型化设计;同时贴片式结构支持自动化生产,提升量产效率,降低人工成本。

四、电气性能解析

  1. 共模干扰抑制能力:700Ω的阻抗针对共模干扰频段(通常为1MHz~100MHz),可有效衰减电路中的共模噪声(如开关电源的高频纹波),避免设备对外辐射干扰(满足EMC认证要求),或受外部干扰影响稳定性(如通信设备的信号误码、工业PLC的误触发)。
  2. 低损耗设计:6mΩ的DCR显著降低功率损耗(计算公式:(P=I^2×R),8A时损耗仅0.384W),减少设备发热,延长使用寿命,尤其适合对效率敏感的电源电路(如笔记本适配器、LED驱动电源)。
  3. 宽温域可靠性:-40℃~+125℃的工作范围覆盖了工业环境(如冷库、高温车间)与户外消费电子(如车载充电器)的温度需求,无需额外散热设计,保障长期稳定运行。

五、典型应用场景

SMCM1211-701T的参数特性使其适配多领域应用:

  1. 消费电子:电源适配器(手机、笔记本充电器)、机顶盒、路由器——抑制开关电源EMI噪声,满足3C/CE等电磁兼容认证。
  2. 工业控制:PLC模块、伺服驱动器、小型变频器——宽温域适应工业现场,8A电流满足中功率控制电路滤波。
  3. 汽车电子:车载充电器、仪表盘电源(低压系统)——宽温与抗干扰能力适配车载环境(-40℃~85℃常规车载温域)。
  4. 通信设备:交换机、光模块电源——减少信号干扰,提升数据传输稳定性。

六、品牌与可靠性保障

顺翔诺(SXN)作为专业电子元器件品牌,SMCM1211-701T遵循严格的生产工艺与质量管控:

  • 绝缘电阻与耐电压参数符合GB/T 15287、IEC 61000-4-2等EMC安全标准,保障电气安全;
  • 宽温域测试通过高低温循环老化(-40℃~125℃循环100次),确保极端环境下性能稳定;
  • 贴片封装的焊接可靠性符合IPC-A-610标准,适配无铅焊接工艺,支持环保生产。

该产品以“小体积、中功率、高可靠性”为核心优势,是工业与消费电子领域抑制共模干扰的高性价比选择。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
