Common Mode Choke 100mA


Common Mode Choke

The Common Mode Choke with Part No: TCMC7FNT101-RD is a specialized component designed for automotive applications, specifically tailored for use in 100 Base-T1 Ethernet networks with Power over Data Lines (PoDL) support. Its 1812 size makes it compact and suitable for integration into various electronic systems. This choke is engineered to handle a maximum current of 100mA and operate within a voltage range of up to 60VDC, ensuring reliable performance in automotive environments where voltage fluctuations and noise suppression are critical.

Furthermore, this Common Mode Choke is classified as Automotive Grade, meeting stringent quality standards and reliability requirements 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 paramount. Its compact size, combined with its ability to handle PoDL and common mode noise, makes it an essential component for ensuring robust and stable data and power transmission in automotive Ethernet networks.

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.
