The CMS1-14-R devices are a type of common mode chokes that are widely used to reduce interference generated by electromagnetic fields. Common mode chokes are used to suppress Common Mode currents, which are the intentional or unintentional electric currents that flow from one electrical conductor to another through random directions of return paths.

CMS1-14-R devices are best suited for applications that require low insertion loss and high attenuation. They are typically used in high voltage and frequency environments with tight tolerance requirements. Common environments include automotive, aerospace, and military applications. Common applications include switching power supplies, motor drives, communication equipment, and other high-frequency systems.

CMS1-14-R devices are typically composed of an inductive element, such as a coil or transformer, connected between two or more electrical conductors. The inductive element is designed to suppress common mode current and reduce electromagnetic field interference. The inductance of the common mode choke determines the current suppression and electromagnetic field noise reduction.

The working principle of common mode chokes is based on electromagnetic field theory. When an AC signal is applied to the inductive element, the magnetic field produced interacts with the shield and causes an induction current. This induction current is in the opposite direction of the applied signal, resulting in a decrease in the amplitude of the applied signal. This decrease in signal amplitude is known as attenuation and is the basis of common mode choke effectiveness.

CMS1-14-R devices can also be used to filter and reduce electrical noise generated by high frequency circuits. The filter is designed to suppress any unwanted electrical noise and reduce interference. The inductor of the common mode choke is designed to attenuate noise by creating an impedance in the circuit that the noise has to pass. This impedance acts as a barrier and the noise is attenuated as it passes through the inductor of the common mode choke.

Common Mode chokes are typically found in a variety of applications that require low insertion loss and high attenuation performance. They are used in motor drives, switchers, communication equipment, automotive, and aerospace applications where strongFilter levels are important. The strong filter levels helps protect delicate cords from interference generated by electromagnetic fields. Additionally, common mode chokes with low insertion loss can be used for filtering and attenuating high frequency noise.
