Fixed inductors, such as 2256R-32K, are vital components found in modern electronic systems. They are used to store energy in an electromagnetic field and generate a small ac current when alternating current is applied. A fixed inductor consists of a coil of wire surrounded by a ferromagnetic core. The core concentrates the field generated by the wire, increasing the inductor’s inductance.

The 2256R-32K is a high quality power inductor designed for application in DC/DC converters and power supplies. It has a rated inductance of 32,000 μH with a low DC resistance of only 0.13Ω. This inductor is fully rated for currents up to 15A, and can withstand operating temperature up to 130°C. The 2256R-32K is available in an 18-pin DIP case, making it an ideal choice for high-current applications.

The working principle of a fixed inductor is based on Faraday’s law of electromagnetic induction. According to this law, when a voltage is applied across a coil of wire, a current is induced in it. This induced current creates a magnetic field around the coil, which in turn induces a voltage in the coil. The amount of voltage induced is proportional to the rate of change of the magnetic flux, which is determined by the magnitude of the current passing through the coil.

The important parameters of a fixed inductor are the inductance, core material, current-handling capacity, and temperature range. The inductance of a fixed inductor is determined by the number of turns in the coil, the core material used, and the geometry of the core. The current-handling capacity depends on the wire size and the type of core used, and the temperature range is determined by the insulation material used for the coil. With the 2256R-32K, these parameters offer excellent performance in high-power applications.

In conclusion, the 2256R-32K is an excellent choice for any high-power application due to its high Rated inductance of 32,000 μH, low DC resistance of only 0.13Ω, high current-handling capacity up to 15A, and wide operating temperature range up to 130°C. The working principle of the fixed inductor is based on Faraday’s law of electromagnetic induction, which means that the induction generated in the coil is proportional to the rate of change of the magnetic flux, which in turn is determined by the magnitude of the current passing through the coil. The important parameters of a fixed inductor, which determine its performance, are the inductance, core material, current-handling capacity, and temperature range.
