Fixed inductors are electronics components of various types and sizes which can be used for a variety of applications. They are typically found in electronic circuits as a part of active or passive components, such as resistors and capacitors.CEI122BNP-1R2MC is a specific type of fixed inductor, which has a rectangular core made from ferrite material. This type of fixed inductor usually has two pins, which are the terminals for electrical connection. It also has a label at the side indicating the values of the inductance and the rated current.The application field of the CEI122BNP-1R2MC fixed inductor is mainly in DC-DC power supplies, such as those used for mobile phones and other electronic devices. It could also be used as filter inductor in other applications.The working principle of a fixed inductor is based on electromagnetic induction. A voltage is applied to the terminals of the inductor, causing a current to flow through the core and generated a magnetic field around it. This magnetic field induces a voltage on the coil, which is opposed to the applied voltage. This electromagnetic opposition is called inductance and is responsible for the electrical energy generated.The electromagnetic behaviour of a fixed inductor can be calculated by employing the principles of Faraday’s law. The value of inductance can be determined by measuring the current through the inductor when a voltage is applied. The higher the voltage applied to an inductor, the higher the opposing voltage generated by the inductor.In general, fixed inductors can be categorized into different types based on their shape, material, core type and size. The CEI122BNP-1R2MC is a type of fixed inductor with a ferrite core, which is mainly used in DC-DC power supplies. Its application field and working principles can be used to identify this type of inductor and understand its properties.
