Understanding 9 Different Types Of Choke
Through the use of an electrical component called a choke, low frequency signals can pass through while high frequency signals are blocked. It is frequently used to filter out unwanted noise and interference in electronic circuits. There are several different types of chokes available, each with its own unique properties and applications. In this post, we will explore 9 different types of chokes and their functions.
Common Mode Choke
A common mode choke is used to suppress common mode noise, which is noise that is present on both the signal and ground lines of a circuit. It is often used in power supplies and other high voltage applications. The choke consists of two coils wound around a magnetic core, with the signal and ground lines passing through the center of the coils.
Differential Mode Choke
A differential mode choke is used to filter out differential mode noise, which is noise that is present on the signal line but not the ground line. It is often used in audio and data transmission circuits. The choke consists of two coils wound around a magnetic core, with the signal line passing through one coil and the ground line passing through the other.
RF Choke
An RF choke is used to block radio frequency (RF) signals from entering or leaving a circuit. It is often used in antenna and RF amplifier circuits. The choke consists of a coil of wire wound around a magnetic core, with the signal line passing through the center of the coil.
Power Choke
A power choke is used to filter out noise and interference from a power supply. It is often used in audio amplifiers and other high current applications. The choke consists of a coil of wire wound around a magnetic core, with the power supply line passing through the center of the coil.
Ferrite Bead
A ferrite bead is a small cylindrical choke that is used to block high frequency noise. It is often used in computer and audio cables to reduce electromagnetic interference. The bead consists of a ferrite core surrounded by a coil of wire.
SMD Choke
Surface mount devices, or SMDs, are used in electronic circuits as chokes. To remove noise and interference, it is frequently used in audio and video equipment. The signal line runs through the center of a wire coil that is wound around a magnetic core to create the choke.
Line Filter Choke
A line filter choke is used to filter out noise and interference from a power supply. It is often used in audio and video equipment to improve signal quality. The choke consists of a coil of wire wound around a magnetic core, with the power supply line passing through the core of the coil.
Air Core Choke
An air core choke is used to filter out noise and interference from a circuit. It is often used in audio and video equipment to improve signal quality. The choke consists of a coil of wire wound around a non-magnetic core, such as a plastic or ceramic rod.
Balun
A balun is a type of choke that transforms signals from balanced to unbalanced. To match impedance and lower noise, it is frequently used in antenna and audio circuits. The input and output lines pass through the center of the two coils that make up the balun, which are wound around a magnetic core.
Chokes are an important component in electronic circuits that are used to filter out noise and interference. There are several different types of chokes available, each with its own unique properties and applications. Understanding the different types of chokes and their functions can help you choose the right component for your specific application.
