Common mode chokes (CMCs) are components that are used as an element in the control, filtering, EMI suppression and signal noise reduction circuits. They are used mainly in electric power, lighting and electronic systems. Common-mode chokes in automotive applications are used to suppress interference from electronic components, such as electric motors, speed controllers, power electronics and power lines. The PLY10AN3521R0D2B is a CMC with a rated current of 10A and a rated voltage of 3521V.The purpose of a CMC is to restrict the transfer of current in both directions across its winding. When current flows in one direction, it is blocked or reduced in the opposite direction. In order to achieve this, the CMC consists of two identical coils wound in opposite directions. This creates a differential mode (DM) of operation where the coils cancel each other out and only allow current to pass in one direction.The PLY10AN3521R0D2B has been designed for noise immunity and EMI suppression in automotive control and power systems. It has a minimum inductance of 3mH, which is ideal for reducing RF noise, and a low capacitance of 150pF, which helps to reduce EMI. The component is also very stable at high temperatures and can withstand up to 125°C. It also has a long lifetime of up to 10,000 hours.In terms of applications, the PLY10AN3521R0D2B is an excellent choice for automotive systems such as motor controllers, power boards, inverters, and high-current power lines. The component is also ideal for the automotive electric powertrain control system, such as EV/HEV, hybrid cars, and autopilots. It is also suitable for high-current automotive charging systems, which need to be protected from EMI and noise pollution.In terms of its working principle, the PLY10AN3521R0D2B component works by stopping any differential current from flowing through the winding. When the CMC is in its differential operating mode, the ends of the two coils are open-circuit, and current going in one direction is hindered by the fact that it has to somehow pass through the other coil in an opposite direction. This prevents the AC common-mode current from flowing, thus suppressing the noise.In conclusion, the PLY10AN3521R0D2B is a highly effective, cost-efficient, and reliable CMC for automotive control and power systems. Its minimum inductance of 3mH and low capacitance of 150pF make it ideal for EMI suppression and reducing RF noise. The component has a rated current of 10A and a rated voltage of 3521V, making it suitable for high-current automotive applications. It is also designed for a long lifetime of up to 10,000 hours and can withstand temperatures of up to 125°C, making it an excellent choice for automotive systems.
