YLCM0905C-202T共模滤波器产品概述

一、产品定位与核心功能

YLCM0905C-202T是益嘉源(YJYCOIN)推出的双路表面贴装共模滤波器,核心作用是优化电子设备的电磁兼容(EMC)性能——通过抑制电路中的共模干扰信号,减少设备对外的电磁辐射,同时提升自身抗干扰能力。

共模干扰是指同时叠加在两根导线(如电源线正负极、差分信号线)上、相位一致的干扰(如电源纹波、射频串扰)。该器件利用电感的“共模阻抗特性”,将共模干扰转化为热能消耗,且对有用的差模信号(如数据传输、电源输出)衰减极小,实现“滤波不影响信号传输”的设计目标。

二、关键参数深度解析

产品核心参数直接决定应用场景与性能表现,具体解析如下:

  1. 通道数:2
    双路独立滤波设计,可同时处理两路信号(如电源线L/N、USB差分线),无需额外并联器件,简化电路布局。
  2. 电感量:2mH@1kHz
    1kHz低频段下电感值达2毫亨,对低频共模干扰(如工频噪声、电源纹波)抑制能力强,适合需要过滤低频噪声的电路。
  3. 额定电流:600mA
    连续工作允许的最大电流,适配中小功率电路(如5V/3.3V电源、小型传感器供电);超过该值可能导致电感饱和,滤波性能下降。
  4. 阻抗:3kΩ@10MHz
    10MHz高频段下共模阻抗达3千欧,对射频干扰(如无线信号串扰、电磁辐射)抑制效果显著,覆盖从低频到射频的宽干扰频段。
  5. 额定电压:50V
    工作电压上限(直流或交流峰值),满足大多数低压电子设备的电压需求,避免过压损坏。
  6. 直流电阻(DCR):420mΩ
    线圈直流电阻仅0.42欧,相同电流下功耗(I²R)极低,长时间工作发热小,提升设备可靠性。
  7. 工作温度:-40℃~+80℃
    宽温范围覆盖工业级环境(如户外设备、车载系统),可在极端温度下稳定工作。
  8. 绝缘电阻:10MΩ
    绕组与引脚/外壳之间绝缘性能良好,确保电气安全,避免短路风险。

三、封装与物理特性

该产品采用表面贴装(SMD)封装,尺寸为9.2mm(长)×6mm(宽)×5mm(高),具备以下优势:

  • 贴片式设计:适合自动化贴装生产,提高效率、降低人工成本;
  • 紧凑体积:可嵌入高密度PCB设计,节省板上空间,适配便携式电子、小型通信模块等小型化设备。

四、核心性能优势

  1. 宽频段干扰覆盖:低频1kHz电感2mH+高频10MHz阻抗3kΩ,实现从低频纹波到射频干扰的全频段抑制;
  2. 低功耗高可靠性:420mΩ低DCR减少发热,600mA额定电流适配中小功率场景,宽温范围提升环境适应性;
  3. 双路集成简化设计:单器件完成两路信号滤波,无需额外并联,降低PCB布局复杂度;
  4. 安全合规:50V额定电压、10MΩ绝缘电阻,符合电气安全标准,减少设备认证风险。

五、典型应用领域

YLCM0905C-202T适用于多类需要EMC优化的电子设备:

  • 工业控制:PLC输入输出模块、传感器接口电路,抑制现场电磁干扰;
  • 消费电子:智能家居设备(智能音箱、传感器)、小型家电的电源滤波,减少EMI辐射;
  • 通信设备:小型路由器、无线蓝牙模块的信号滤波,提升传输稳定性;
  • 车载电子:车载辅助系统(倒车雷达、胎压监测)的抗干扰,适应宽温环境;
  • 医疗仪器:小型监护仪、血糖检测仪的信号滤波,确保测量精度。

六、总结

YLCM0905C-202T共模滤波器通过双路集成、宽频段滤波、低功耗与宽温适应性,平衡了性能与成本,是工业、消费、通信等领域电子设备EMC优化的实用选择,可有效提升设备的抗干扰能力与电磁兼容性。

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.
