Common Mode Chokes are electromagnetic components used to suppress unwanted EMI (electromagnetic interference) from entering and exiting electronic devices and circuits. The SS28V-K20115-CH is a type of Common Mode Choke; specifically, it is a surface mount, wide band, low impedance, differential-mode EMI filter designed to provide EMI reduction in high frequency applications.

Application Field

The SS28V-K20115-CH is used to reduce EMI on a wide range of digital and RF signals. Its wide input range of 10kHz to 13GHz ensures that it can effectively suppress EMI at any frequency in this range. This makes it suitable for applications such as radio, communications, consumer electronics, automotive electronics, and industrial systems. It is also suitable for applications where frequency hopping or spread spectrum transmitting technologies are used.

Working Principle

The SS28V-K20115-CH works by blocking the currents from digital signals or wideband RF signals which radiate from the ends of the traces and cables. This process increases the impedance between the two paths, which reduces the EMI levels that occur and can interfere with other electronic components. The choke is composed of two windings, a primary winding and a secondary winding, around a ferrite core. The primary winding is connected to the source, while the secondary winding is connected to the load. The two windings act together to form a magnetic field, which suppresses the EMI. The choke is also designed with a low impedance, differential-mode filter. This filter helps to reduce the high frequency noise that is commonly produced by digital signals, or signals that operate at high frequencies. This helps to reduce the effects of EMI on sensitive circuits. In addition to the low impedance, differential-mode filter, the SS28V-K20115-CH also contains two high-pass filters. These filters are designed to suppress the high frequency EMI that is commonly emitted from digital signals. The high-pass filters help to reduce the amount of high frequency noise that is radiated from the choke, and therefore reduce the overall EMI level.

Conclusion

The SS28V-K20115-CH is a type of Common Mode Choke that is designed to reduce EMI levels in high frequency applications. It is composed of two windings, a primary and a secondary, with a ferrite core. The two windings form a magnetic field which acts to suppress the EMI. In addition to this, the choke includes a low impedance, differential-mode filter and two high-pass filters, which help to further reduce EMI levels.
