Common Mode Choke 350mA


Common Mode Choke

The TCMCFNT101-RD Common Mode Choke is a specialized component designed for use in automotive applications, specifically tailored for 100 Base-T1 networks with Power over Data Lines (PoDL) support. Its 2518 size makes it suitable for integration into electronic systems where space is a consideration but robust performance is essential. With a maximum current handling capacity of 350mA and an operating voltage range of up to 60VDC, this choke provides effective common mode noise suppression while ensuring reliable power and data transmission in automotive network environments.

Furthermore, the TCMCFNT101-RD Common Mode Choke is classified as Automotive Grade, meeting rigorous quality and reliability standards set by the AEC-Q200 standard. This designation signifies its suitability for use in automotive electronics, where durability, stability, and adherence to industry standards are critical. By effectively reducing common mode noise and maintaining signal integrity, this choke plays a crucial role in enhancing the overall performance and reliability of automotive network systems, ensuring optimal functionality even in challenging operating conditions.

Typical Applications of Common Mode Chokes Include:

  • Aviation
  • Automotive
  • USB 2.0
  • LVDS
  • High Speed Data Lines
  • LAN

The 2 Line Common Mode Chokes Surface Mount are specialized components utilized to effectively reduce and refine common mode noise in network applications. These chokes are designed to address common mode interference, which occurs when unwanted signals travel along the transmission lines in the same direction. By incorporating these chokes into network circuits, they can mitigate such interference, ensuring cleaner and more reliable data transmission.

These chokes are typically surface mountable, allowing for easy integration into circuit boards commonly used in networking equipment. Their primary function is to provide impedance to common mode signals while allowing differential mode signals to pass through unimpeded. This selective filtering helps to maintain signal integrity and minimize disruptions caused by common mode noise, ultimately enhancing the overall performance and stability of network communication systems.
