Common Mode Chokes are a type of cable ferrite choke used in applications where control of common-mode noise is essential. The most common type and variety of common mode choke is a ceramic core type, designed for use in digital and analog circuits. They are usually used for high frequency noise reduction above 2 MHz and sometimes up to 200 MHz. Common-Mode Chokes have two main types of applications, one is power distribution systems, and the other is disconnection of signal lines.

SSHB21HS-30013 Common Mode Choke Application

The SSHB21HS-30013 Common Mode Choke is designed especially for microphone, audio, digital, broadcast, computer, telecommunications and automotive applications. It can effectively filter out noises and EMI from the common-mode noise in the wire, eliminating signal distortion due to the noise wave and providing maximum protection and audio clarity. Moreover, it can be used to reduce undesired conductive emissions by preventing line noise from inducing currents into the feedback loop of sensitive equipment.

SSHB21HS-30013 Common Mode Choke Working Principle

An SSHB21HS-30013 Common Mode Choke works by wrapping the conductor with a ferrite core. The ferrite core is an electromagnetic material with a high permeability which can effectively store energy. When the signal passes through the choke, the ferrite material blocks the common-mode noise, and the desired signal is passed through while the unwanted noise is redirected away.

The ferrite material is designed to absorb the EMI/RFI signals and allow only the desired signal to pass through. The ferrite core also adds some resistance to the signal which attenuates the noise, making the signal more stable and less affected by external interference. The choke also acts as a filter for high-frequency noise and spikes, thus allowing the desired signal to remain clean and unaffected.

In addition to its noise absorption properties, the choke also provides protection against electrostatic discharge (ESD), which can damage sensitive electronics. It limits currents generated by ESD, thus protecting sensitive equipment from damage. The choke also provides isolation from ground, providing protection for potentially sensitive equipment from power surges.

SSHB21HS-30013 Common Mode Chokes can be used in a variety of applications, from high frequency audio systems to computer networks, from automotive and manufacturing industries to broadcast and video. They are a cost-effective and reliable solution for noise and ESD protection.
