Common mode chokes are devices used to limit the amount of common mode current flowing through a circuit or system. The SU9H-R02140 is a common mode choke designed for use in telecommunications applications. It is a high-performance, surface-mount device designed for filtering and RF isolation in communications systems.

The SU9H-R02140 consists of a pair of ferrite cores with an air gap between them. The cores are wound with two identical coils, each with a diameter of 12.5mm and an inductance of 3.2uH. The two coils are connected in series and form a single winding with a total inductance of 6.4uH. The choke also features a metal shield casing for improved EMI performance.

The SU9H-R02140 is designed to provide a high level of filtering and RF isolation in telecommunications systems. It is designed to reduce common mode currents and noise across a wide range of frequencies, from 1kHz to 1GHz. The choke can be used to filter and shield cables, ensure EMI shielding, and provide RF isolation. It can also be used in conjunction with a common mode choke filter to attenuate any high frequency signals on the line.

The working principle of the SU9H-R02140 is simple. The two coils act as inductors and introduce an inductance into the circuit. This inductance in turn creates a magnetic field around the device, and this field is used to limit the amount of common mode current flowing through the circuit or system. By reducing the amount of common mode current, the device is able to reduce both EMI interference and line noise, thus improving the performance of the system as a whole.

In summary, the SU9H-R02140 is a high-performance common mode choke designed for use in telecommunications applications. It is designed to reduce common mode currents and noise across a wide range of frequencies, from 1kHz to 1GHz. Its working principle is simple – it introduces an inductance into the circuit which in turn creates a magnetic field which limits the amount of common mode current. By reducing the amount of common mode current, it is able to reduce both EMI interference and line noise, thus improving the performance of the system as a whole.
