Fixed inductors, also known as chokes, are electronic components in electrical circuits used mainly to store energy in magnetic fields. They are composed of a coil of wire wound around a core. The core can be made of ferrite, powdered iron, or other materials such as air. Fixed inductors are used to block out or limit frequencies from passing through them. When an alternating current is applied to an inductor, a back-emf is generated in the inductor. This back-emf prevents current from changing too quickly within an electrical circuit.

TYS4020220M-10 is a fixed inductor from MuRata. It is rated with an inductance of 2.2μH and a DC current of 5000mA. It is packaged in a 4020 surface-mount plastic or 1210 molded, both with a shielding ferrite core. The operating temperature range of this fixed inductor ranges from –25°C to 85°C as specified in its datasheet.

This fixed inductor is mainly used in switching power supplies, DC-to-DC converters, and DSP circuits. Other applications include low-noise filters, audio amplifiers, and switching regulators. When used in DC-to-DC converters, the TYS4020220M-10 works by limiting the voltage ripple during the step-down process, thus providing a stable output voltage.

The working principle of the TYS4020220M-10 is based on Faraday’s law of induction. According to Faraday’s law of induction, when the current through an inductor changes, a voltage is induced with a magnitude that is proportional to the rate of change of the current. This generated voltage (back emf) opposes the changing current, and thus acts as an inductor. This principle can be used in DC-to-DC converters to provide a stable output voltage.

Overall, the TYS4020220M-10 fixed inductor is an ideal component for a variety of applications, such as in switching power supplies, DC-to-DC converters, and audio amplifiers. With its low profile surface-mount plastic and high current rating, this fixed inductor is a great choice for any design.
