Common Mode Chokes

The ZJYS81R5-2P24T-G01 is one type of common-mode choke that is an electromagnetic component designed to reduce certain types of signals, known as differential mode signals. Common mode chokes are widely used in many different types of electrical systems, from power supplies to digital signal processors (DSPs).

Application Field:

A common purpose of using a common mode choke is to act as an electrical filter. They are used in a variety of applications such as high frequency filter circuits, telecommunications systems, medical equipment, and more. They act as a barrier to currents that are trying to pass through them, which can be used to block a certain type of signal.

Common mode chokes are also used in power supplies to reduce electrical noise and help maintain a stable voltage output. They act as a low-pass filter, which means that they allow lower frequencies to pass through but not higher ones. In digital circuits, this is especially important since high frequency signals can cause interference with the signals the circuit is meant to process. Common mode chokes can also be used in radio antenna systems to reduce interference from other signals.

Working Principle:

A common mode choke works by allowing some types of signals to pass through it, while blocking or attenuating certain types. The two main types of chokes that can be found in the market are inductive and capacitive. The type of choke used depends on the application and the desired result.

Inductive common mode chokes are made of a coil of wire wrapped around a core material. This creates a magnetic field as current flows through the coil, which in turn creates an opposing electromagnetic field. This field opposes the fields of incoming signals, and prevents them from reaching the output.

Capacitive common mode chokes are made of two plates separated by an insulating material. When an alternating current is applied to one of the plates, an electromagnetic field is created, which opposes the fields of incoming signals, blocking them from reaching the output. Capacitive chokes offer higher levels of signal attenuation than inductive chokes, but are more expensive.

Common mode chokes are used in a variety of applications, from power supplies to digital circuits. They are a necessary component in many electronic systems, as they serve to protect sensitive signals and reduce noise and interference.
