EMI Common Mode Coil for automotive charging

An EMI (Electromagnetic Interference) Common Mode Coil Inductor is a type of Filter Inductor that is used to filter out common mode noise in electronic systems. This type of noise is typically caused by electromagnetic interference and can disrupt the proper functioning of electronic devices.

The common mode coil power inductor works by creating a high impedance path for common mode noise, effectively blocking it from passing through the system. This is achieved by winding two coils in opposite directions around a common core. When a common mode noise signal enters the inductor, it induces equal and opposite magnetic fields in the two coils, which cancel each other out and prevent the noise from passing through.

This type of High Current Inductor is commonly used in power supply units, communication equipment, and other electronic devices such as for automotive charging.
