The 0819-72H also provides excellent inductance accuracy over the entire temperature range, along with very low DC resistance and excellent thermal characteristics.

Working Principle

The basic working principle of a fixed inductor is very simple. When current passes through the inductor, it creates an electromagnetic field that stores energy in the form of a magnetic field. When the current is switched off, this magnetic field collapses, releasing the stored energy into the circuit, acting like a voltage source.By winding many turns of wire around an inductor core, it is possible to increase the inductance. The actual value of inductance is determined by the geometry of the wire, the number of turns, and the core material. In addition, the inductance can be increased further by adjusting the air gap between the turns of the inductor.
