Common Mode Chokes are widely used in a number of different applications to filter out undesirable common-mode interference signals. The TLF14CBH8020R8 common mode choke is a ideal choice for applications that require a high voltage common-mode choke, such as telecommunications, industrial, medical, and home entertainment systems. The TLF14CBH8020R8 provides good suppression of both its high- and low-frequency common-mode noise, making it an excellent choice for applications where both are a concern.

The TLF14CBH8020R8 common mode choke is designed to suppress a wide range of frequencies, from 10kHz to 1GHz. It is rated for up to 80Vrms of common-mode voltage and up to 2A of common-mode current. The product provides excellent attenuation of common-mode noise over this frequency range, with an insertion loss of up to -40dB. The inductance of the TLF14CBH8020R8 ranges from 100µH to 570µH depending on current and frequency.

The TLF14CBH8020R8 common mode choke\'s working principle consists of two main parts: a ferrite core and copper winding in a core-and-coil configuration. The ferrite core of the TLF14CBH8020R8 is made from a ferrite material that has a very high permeability, meaning it is able to store more energy in a magnetic field. The copper winding is designed to generate a magnetic field that is in opposition to the current flowing through the choke.

When a common-mode signal is applied to the TLF14CBH8020R8, the current flowing through the choke creates a magnetic field around it which is in opposition to the external common-mode signal. This action serves to create counter electromotive forces that reduce the amplitude of the common-mode signal. The amount of suppression depends on the strength of the magnetic field generated by the choke and the amount of current flowing through it.

The TLF14CBH8020R8 common mode choke can also be used to suppress differential-mode signals. It is designed so that the same magnetic field generated by the ferrite core and copper winding can also be used to suppress differential-mode signals. This is achieved by using two windings for each differential-mode signal, with one winding in each core. The differential-mode current flows through both windings, so the magnetic fields generated by both windings cancel each other out and therefore reduce the amplitude of the differential-mode signal.

The TLF14CBH8020R8 is a versatile common-mode choke and can be used in a variety of different applications, such as telecommunications, industrial, medical and home entertainment systems. It is designed with a wide frequency response, up to 1GHz, and a high common-mode impedance, making it an excellent choice where both factors are a concern. The choke is also capable of suppressing unwanted common-mode and differential-mode noise, making it an effective choice for any application where noise suppression is a priority.
