Ferrite Cores - Cables and WiringFerrite cores are magnets composed of iron and other ferrous materials, used for various applications ranging from power conditioning to noise attenuation. The CA28B0937 is a ferrite core that can be used in a variety of contexts, from inductors and transformer cores to EMI/RFI filters. In this article, we will discuss the application fields and working principle of the CA28B0937.The CA28B0937 is a specialized Ferrite core designed for use in power conditioning applications, where it can provide both protection from high voltage spikes and electromagnetic interference (EMI) attenuation. It is ideally suited for use in automotive, industrial and military applications, due to its superior ability to absorb higher levels of EMI. The CA28B0937 is composed of an outer ferrite core and an inner core that is designed to attenuate incoming EMI and provide the necessary ESR for power conditioning purposes.In terms of application fields, the CA28B0937 can be used for a variety of purposes, including power conditioning filters, inductors, transformers, switch mode power supplies, and EMI/RFI filters. In addition, it can also be used to build very high-frequency resonators, such as shorted turn or high-damping filters. The power conditioning filter applications is where the CA28 promises the best performance, as it is designed to have low inductance, low ESR, and excellent isolation from high frequency transients. This combination of characteristics is perfect for protecting sensitive electronics from power line spikes and interference.When it comes to the working principle of the CA28B0937, its ability to attenuate EMI and power line transients can be attributed to two effects: inductive and capacitive. The first effect is inductive, as the CA28\'s ferrite core is designed to provide the necessary inductance for power conditioning purposes. The CA28 also has a very low impedance, which allows it to provide the necessary impedance needed to condition the power lines. This makes it ideal for use in power conditioning filters, as it can provide significant attenuation of high-frequency transients.The CA28B0937\'s second effect is a capacitive one. The ferrite core absorbs the EMI, and the inner core, made of a material that has a higher dielectric constant, acts as a capacitor. This allows the CA28 to attenuate EMI very efficiently, as the current generated by the EMI is absorbed. This means that the CA28 is an effective EMI filter that can reduce interference to a much greater degree than many other ferrite cores.Overall, the CA28B0937 is a specialized ferrite core that is perfect for power conditioning, EMI/RFI filtering applications. Its low inductance, low ESR, and high capacitance make it ideal for absorbing various levels of EMI and protecting sensitive electronics from voltage spikes. As such, it is an invaluable component in today\'s power conditioning and EMI/RFI filters.
