YLM3225-102T共模滤波器产品概述

YLM3225-102T是益嘉源(YJYCOIN)推出的一款小型化表面贴装(SMD)共模滤波器,专为抑制电子电路中的高频共模噪声设计,具备高阻抗、低损耗、小体积等核心特点,可有效提升设备电磁兼容性(EMC),适配多种低压小电流应用场景。

一、产品核心定位

该器件属于双路共模滤波器件,针对100MHz频段高频噪声抑制优化,采用紧凑SMD封装,核心解决小型化电子设备中信号传输与电磁干扰的矛盾——既不影响信号的直流/低频正常传输,又能高效衰减共模噪声,满足消费电子、IoT、通信等领域的EMC合规要求。

二、关键性能参数详解

YLM3225-102T的参数围绕「滤波能力、传输损耗、可靠性」三维度设计,核心参数如下:

  • 通道数:2路双端共模滤波,支持两路信号同步滤波,无需额外并联器件;
  • 额定电流:400mA(连续工作电流),覆盖多数低压小电流电路的电流需求;
  • 共模阻抗:1kΩ@100MHz(核心滤波指标),100MHz频段高阻抗可有效衰减射频杂散、高速数字电路噪声;
  • 额定电压:50V(AC/DC通用),适配低压电路工作范围;
  • 耐电压:125V(短时间耐受),为绝缘可靠性提供冗余,降低过压损坏风险;
  • 直流电阻(DCR):300mΩ/通道,低损耗避免信号压降,适合敏感信号电路;
  • 绝缘电阻:≥10MΩ,引脚间及与外壳绝缘满足安规要求,防止漏电;
  • 封装尺寸:3.2×2.5×2.2mm(长×宽×高),超小型SMD封装适配高密度PCB。

三、封装设计特点

该产品采用表面贴装封装,尺寸仅3.2×2.5×2.2mm,具备以下设计优势:

  1. 小体积高密度:尺寸接近0805封装量级,可直接集成到小型设备PCB中,节省布局空间;
  2. 贴片工艺适配:无插件引脚设计,支持自动化回流焊、波峰焊,生产效率高;
  3. 耐温性稳定:符合常规SMD回流焊温度曲线(峰值260℃左右,时长≤10s),焊接不损坏器件;
  4. 引脚兼容性:引脚间距适配常规焊盘设计,无需特殊布局调整。

四、核心技术优势

对比同类产品,YLM3225-102T的核心优势体现在:

  1. 高频滤波精准:100MHz频段1kΩ阻抗,精准抑制WiFi/蓝牙杂散、高速数字噪声;
  2. 低损耗传输:300mΩ低直流电阻,避免信号功率衰减,适合敏感电路;
  3. 高可靠性设计:耐电压125V(额定电压2.5倍)、绝缘电阻≥10MΩ,应对瞬时过压;
  4. 宽场景适配:50V电压、400mA电流,覆盖消费电子、IoT、工业控制等多领域。

五、典型应用场景

该器件适配多种低压小电流应用:

  1. 消费电子:智能手机、平板的WiFi/蓝牙射频电路,抑制信号杂散;
  2. IoT设备:智能穿戴(手表/手环)、智能家居传感器(温湿度、运动)的信号滤波;
  3. 通信终端:无线AP、小型基站接口电路,满足EMC合规;
  4. 工业控制:小型PLC、远程IO模块的输入输出滤波,提升抗干扰;
  5. 车载附件:车载USB、蓝牙模块的EMI抑制(可拓展至车规场景)。

六、使用注意事项

为确保性能可靠,使用需注意:

  1. 焊接工艺:遵循回流焊曲线(预热150-180℃,峰值250-260℃,时长≤10s),避免过热;
  2. 电参数限制:连续电流≤400mA,电压≤50V;短时间耐125V,但不可长期超压;
  3. 绝缘防护:PCB布局时,引脚与地、相邻引脚距离≥0.5mm,防止漏电;
  4. 存储条件:常温(25±5℃)、干燥(湿度≤60%)环境,开封后1个月内使用。

综上,YLM3225-102T是高性价比的小型化共模滤波器,可有效解决高频共模噪声问题,是消费电子、IoT等领域提升EMC性能的理想选择。

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.
