Common Mode Chokes (CMC) are devices used in electrical engineering to suppress high frequency interference and Radio Frequency Interference (RFI). EV28-5.0-02-1M1 is a type of CMC specially designed for industrial and telecommunications applications. This article will discuss the EV28-5.0-02-1M1’s application fields and working principle.

Application Fields

The EV2 Series Common Mode Chokes have broad application fields in telecommunication systems, such as CATV, HFC and xDSL systems.These types of CMCs are suitable as input filters of various high-frequency modules, like amplifier modules, tuner modules, signal source modules, as shielding components, for reducing the instability and noise of the whole system. EV2 Series Common Mode Chokes are available in 4 versions: 12A, 10A, 8A and 6A, each supplying different Inductance from 18.2 nH to 33.2 nH. The wide variety of product characteristics can cater for an extremely broad range of applications.

Working Principle

The working principle of EV28-5.0-02-1M1 is based on the principle of electromagnetic induction, a technique used to convert electrical power into electromagnetic energy. The core material used to make the part magnetically shielded is made of ferrite, which is chosen because of its high permeability. The use of the ferrite core in the CMC helps reduce the inductance in the external circuit, which in turn reduces the energy that could be wasted in the system.

The EV28-5.0-02-1M1 also has an internal high permittivity shield, which further reduces the noise that could be generated from the device. This shield together with the ferrite core in the CMC helps to reduce the amount of electro-magnetic interference (EMI) generated from the device.

The EV28-5.0-02-1M1 also features built-in low-temperature coefficient and stability capacitor, which helps to reduce the temperature rise and improve the operation stability of the device. This helps reduce the possibility of high frequency disturbances that could be caused by the device in the external circuit.

Conclusion

In conclusion, EV28-5.0-02-1M1 belongs to the Common Mode Choke family, which is specially designed for industrial and telecommunications applications. The EV28-5.0-02-1M1 has many advanced features, such as its high-density ferrite core, internal high permittivity shield, and low-temperature coefficient and stability capacitor. These features help reduce radiations, noise, and temperature from EV28-5.0-02-1M1 and make it suitable for use in high frequency modules.
