Common Mode Chokes

Common Mode Chokes (CMCs) are widely employed for suppressing electromagnetic interference (EMI) generated by electric power lines, electric motors and other sources of RF interference. The CME2425-3 is a type of CMC designed to attenuate much higher frequencies than traditional CMCs, usually ranging from 30 to 200MHz. This makes it well suited for applications such as medical equipment, test benches and automotive electronics.

Application Field

The CME2425-3 can be used in a variety of applications where noise suppression is necessary, such as:

• Automotive electronics
• Medical Equipment
• Test Benches
• Power Amplifiers
• Extruder Controllers

In terms of automotive applications, the CME2425-3 can be used to eliminate noise generated by engine sensors and other electronics, while in medical equipment applications it can be used to reduce EMI that could potentially interfere with vital signals or medical monitors.

Working Principle

The CME2425-3 works by suppressing EMI noise generated in circuits by passing the current through a magnetic core, forming a closed loop with minimal inductive reactance. This reduces the amount of EMI noise that is passed through to the power line, as the minor loop created by the magnetic core blocks the noise from circulating and passing through the power line. The larger the cross section of the core, the more effective it is in suppressing the EMI noise.

The CME2425-3 also features a unique construction which allows for higher performance compared to traditional CMCs. It has a triple axial construction, with two inner windings and one outer winding. It also has a special high-permittivity spacing between the layers for optimal performance. All of this contributes to its high-frequency filtering capabilities, making it one of the best performing CMCs on the market.

Conclusion

The CME2425-3 is an advanced type of Common Mode Choke designed for high-frequency noise suppression applications. It can be used in a variety of situations, from automotive electronics to medical equipment, thanks to its triple axial design and high-permittivity insulation between the layers. It also features an effective noise suppression system which utilizes a magnetic core to form a closed loop with minimal inductive reactance, reducing the amount of EMI noise that is passed through to the power line. Overall, the CME2425-3 is an excellent choice for applications where high-frequency noise suppression is necessary.
