Ferrite cores are a type of material used as magnetic cores in electronic equipment to reduce electromagnetic interference (EMI). For most applications, a ferrite core will serve as a choke between two conductive elements. A ferrite core reduces EMI by providing an inductance which becomes an obstacle to the flow of high frequency currents. The AS20B2042 is an example of a ferrite core. The AS20B2042 is a ferrite core that comes with a flexible copper winding. It consists of a ferrite core with an inner diameter of 20 mm and an outer diameter of 20 mm. The core is made of copper and iron alloy and it is designed for a range of applications including power supplies, transformers, motors, and signal filtering. The flexible copper winding around the core creates an inductive filter that suppresses high frequency signals by reducing their amplitude.The AS20B2042 ferrite core is designed to reduce power line interference and unwanted signals that can be generated in power supplies and motor circuits. It is used to reduce the electrically coupled oscillations which are generated when high frequency switching currents or high frequency operating frequencies pass through the core. It helps to suppress unwanted frequencies, ensuring that power supplies and motor control systems remain in phase. It is also used in inverter circuits to reduce high-frequency switching interference. The working principle of the AS20B2042 ferrite core is based on the phenomenon of magnetic hysteresis. The core is saturated with the surrounding magnetic field. This causes its permeability to change over time in response to changes in current or voltage. The permeability depends on the frequency of the signal, meaning that higher frequency signals are more strongly attenuated than lower frequency signals. The hysteresis also causes the core to shift the phase of the output signal, further reducing the amount of interference. The AS20B2042 ferrite core serves primarily as a passive filter, meaning that it does not require any external power input and does not influence the signal it is protecting. It is primarily used in applications where the EMI frequencies are known, as it will only suppress signals of predetermined frequencies. It is not suitable for filtering unknown or unpredictable signals. The AS20B2042 ferrite core is suitable for use in a variety of applications where EMI needs to be suppressed. It can be used in power supplies, transformers, motors, signal filtering, and inverters. Its flexible copper winding ensures that the inductive filter is strong enough to reduce high frequency signals, making it an effective tool for reducing interference.The specific data is subject to PDF, and the above content is for reference
