Common mode chokes are a type of power supply filter used to reduce transient noise that affects a circuit’s noise performance. The most common type of common mode choke is the TF2514VU-131Y7R0-01. This type of choke is a ferrite core-based filter.

Application Field

Due to its high impedance properties, the TF2514VU-131Y7R0-01 is an ideal filter for suppressing common mode noise on power lines. This noise can be caused by changes in the current or voltage flowing through the line. It is used primarily in electrical systems that require noise immunity, such as automotive systems, avionics systems, and industrial control systems. It can also be used in medical and military applications.

Working Principle

Common mode chokes are typically constructed from two coils that are wound around a ferromagnetic core. These coils have an equivalent inductance, but the current flowing through them must be equal in magnitude. If the current flowing through the coils is not equal, then a common mode signal will be created. In such a case, the TF2514VU-131Y7R0-01 choke will act as a high-impedance barrier to suppress the noise.

The choke works by diverting the common mode current to ground by absorbing the energy in the form of magnetic flux in the ferromagnetic core. This essentially absorbs and dissipates the unwanted electromagnetic noise before it reaches the power lines, thereby providing noise attenuation.

The choke’s performance depends on several factors, such as the number of windings, the core material, and the external circuit design. It is important to select the right choke for a specific application in order to achieve the best noise reduction performance.

The TF2514VU-131Y7R0-01 common mode choke is a versatile, cost-effective solution for noise reduction in a variety of applications. Its ability to provide high impedance makes it ideal for suppressing common mode noise on power lines. By absorbing and dissipating unwanted electromagnetic noise, it helps to ensure that the desired signal is protected from interference.
