Common Mode Chokes

Common Mode Chokes are electromagnetic components made up of two coils or a single coil in an U-shape usually composed of a few turns. It is widely used in the power and telecommunication systems. A type of common mode choke is the ELF-18D650L which is an inductor mainly used in home appliances.

Application Field of ELF-18D650L

The ELF-18D650L is an advanced common mode choke which is mainly used in home appliances, such as digital equipment, electronic products, switches, relays, etc. It is also used in electrical transmission and power distribution systems.

With its superior performance, this common mode choke can handle large amounts of current (up to 18 amps) and can be used for both AC and DC circuits. It has an excellent resistance to high frequency noise. The ELF-18D650L is usually used for the suppression of unwanted common-mode noise in the system by preventing current from returning back to the source. It can reduce the amount of noise in a system by filtering out the noise from the power supply and other components.

Working Principle of ELF-18D650L

The working principle of the ELF-18D650L is based on the principle of magnetic coupling. This component works by creating a magnetic field when current passes through two coils. The magnetic field created by the two coils is in opposite directions, which helps to reduce noise.

The ELF-18D650L contains two identical windings, which are wound on the same core and have the same number of turns. The windings are connected in series or in parallel, depending on the required application. When AC current is passed through the windings, a magnetic field is created which opposes the current in one of the wires, while the current in the other wire remains unchanged. This makes the ELF-18D650L an ideal component for reducing noise in home appliances.

The ELF-18D650L can also be used for suppressing the radiations from the TV signal or the sound waves from the microphone. The common mode noise which is emitted due to the coupling of different frequencies gets filtered out by the ELF-18D650L, making it an ideal choice for audio or video equipment.

Conclusion

In conclusion, the ELF-18D650L is a common mode choke made up of two coils or a single coil in an U-shape. It is mainly used for suppressing noise in home appliances, as well as in electrical transmission and power distribution systems. The working principle of this choke is based on the principle of magnetic coupling, where two identical windings are wound on the same core. This component is very efficient in eliminating noise in audio and video equipment.
