Common Mode Chokes

Common mode chokes such as the B82720H0014A016 model are electrical components designed to filter out electrical noise in a circuit. These components are used to reject common mode noise, which is electromagnetic noise from an electronic circuit, in order to provide good signal integrity. The B82720H0014A016 is a surface-mount common mode choke, with an operating frequency ranging from 16MHz to 300MHz, and a maximum current rating of 1.5A.

Application Field

The B82720H0014A016 is commonly used in data and signal transmission applications, such as Ethernet, USB, and CAN bus. It is designed to combat any unwanted noise or interference that may disrupt the operation of these systems. It is also commonly found in industrial automation systems, where proper signal integrity is of paramount importance. The B82720H0014A016 can also be used in radio frequency (RF) applications, to filter out interference from radio signals.

Working Principle

Common mode chokes, such as the B82720H0014A016, work by creating a high-impedance path for the unwanted common mode noise. This high impedance serves as an obstacle that reduces the amount of noise that can pass through the circuit. The B82720H0014A016 has two separate windings called the primary and the secondary windings. The primary winding acts as the input for the circuit, while the secondary winding is the output. The primary and secondary windings are oriented in opposite directions, creating an inductance that prevents the common mode noise from passing. This reduces the amount of interference that can enter or leave the circuit and ensures good signal integrity.

Conclusion

The B82720H0014A016 common mode choke is a useful component for electrical systems, such as data and signal transmission applications, industrial automation systems, and radio frequency applications. It works by creating a high-impedance path, which serves as an obstacle that reduces the amount of noise that can pass through the circuit. This ensures good signal integrity and allows the circuit to operate properly.
