SMCM2012-900-2PT 共模滤波器产品概述

一、产品定位与核心价值

SMCM2012-900-2PT是顺翔诺(SXN)推出的超小型表面贴装(SMD)共模滤波器,专为对尺寸、功耗及EMI(电磁干扰)抑制要求严格的小型电子设备设计。其核心价值在于以极小封装实现双路共模干扰过滤,同时兼顾低损耗与宽温适应性,适配消费电子、IoT终端等高密度布局场景,是微型设备解决信号串扰、噪声干扰的高效方案。

二、核心电气参数深度解析

该滤波器的参数围绕“小型化+低损耗+安全可靠”设计,关键指标如下:

  1. 滤波通道与阻抗:双路(2通道)共模滤波结构,目标频段阻抗为90Ω,可有效抑制双路信号线上的共模噪声(如电源线、蓝牙/WiFi模块的信号干扰);
  2. 额定功率范围:额定电流330mA(持续工作电流),支持直流50V、交流125V额定电压,适配低功率电源或信号线路(如5V/1A以下的USB-C适配器);
  3. 损耗与绝缘性能:直流电阻(DCR)仅300mΩ,显著降低功率损耗,适合低功耗设备(如可穿戴设备);绝缘电阻≥10MΩ,耐电压125V(AC),满足基本绝缘安全要求;
  4. 频率适配性:虽未明确标注测试频率,但90Ω阻抗值符合共模滤波器在100kHz~1MHz频段的典型抑制需求(共模干扰高发频段)。

三、封装与结构特性

  1. 超微型SMD封装:尺寸为2×1.2×1.2mm(长×宽×高),属于0402级以下的微型封装,可大幅节省PCB空间,适配可穿戴、TWS耳机等对体积要求苛刻的设备;
  2. 自动化兼容工艺:无引脚SMD结构,兼容高速贴装生产线,生产效率高,适合批量制造;
  3. 材料可靠性:采用耐高温、低损耗的磁性材料与绝缘材料,保证宽温下性能稳定,避免磁饱和或绝缘老化问题。

四、环境适应性表现

  1. 宽温工作范围:-40℃+85℃的工作温度区间,覆盖工业级(-40+85℃)与消费级(-20~+70℃)应用场景,可用于户外IoT终端、车载周边设备等;
  2. 绝缘稳定性:高低温下绝缘电阻保持≥10MΩ,耐电压性能无衰减,避免环境变化导致的绝缘失效,提升设备长期可靠性。

五、典型应用场景与优势总结

5.1 典型应用场景

  • 可穿戴电子:智能手表、手环的蓝牙模块、无线充电线路的共模干扰过滤,避免信号串扰影响续航与连接稳定性;
  • IoT终端:小型传感器节点(温湿度、运动传感器)的电源与信号滤波,保证数据传输无噪声;
  • 低功率电源:5V/1A以下的USB-C适配器、移动电源的输出滤波,抑制开关电源的共模噪声;
  • 消费音频设备:TWS耳机、蓝牙耳机的音频线路滤波,提升音质纯净度,减少电磁干扰杂音。

5.2 核心优势

  • 极小封装:2×1.2×1.2mm尺寸,适配高密度PCB布局,满足微型设备的空间限制;
  • 低损耗设计:300mΩ DCR降低设备功耗,延长电池续航时间;
  • 双路集成:单器件实现双路共模滤波,减少物料数量与PCB占用面积;
  • 宽温可靠:-40~+85℃工作范围,适配多场景应用,无需额外降额设计。

该产品通过平衡尺寸、性能与可靠性,成为微型电子设备EMI抑制的高性价比选择。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
