Fixed Inductors

A fixed inductor, by definition, is an electrical component that stores energy temporarily in a magnetic field. It is composed of two components, a coil and a magnetic core. The bobbin houses the coil, while the core provides a channel for the magnetic field lines. Fixed inductors are used in wide range of electronic applications, ranging from simple filters to more complex power supplies.

The 78F3R3J inductor is a type of fixed inductor designed for use with buck-mode DC-DC converters. The inductor is designed for use in power supply applications, and is capable of handling up to 35 Amps of current. The 78F3R3J inductor has an inductance of 3.8uH and a rated saturation current of 30A.

The 78F3R3J inductor works by storing energy in a magnetic field created by the inductor\'s core and bobbin. When current is applied to the inductor, a magnetic field is created. This magnetic field will cause the inductor\'s core to become saturated, storing a large amount of energy in the magnetic field. As current is applied to the inductor, the magnetic field will grow, thus storing an ever increasing amount of energy.

When the current flow is reversed, the stored energy stored in the magnetic field will be released and transferred back to the circuit. The released energy is then used to create an opposing voltage, which helps to regulate the current flow in the circuit. This helps to reduce or eliminate the effects of voltage spikes and drops, which can occur in circuits where large amounts of current are being used.

The 78F3R3J inductor is a useful tool in many electronic applications, especially in power supply designs. The ability to store energy in a magnetic field and then release it when the current is reversed helps to regulate the current flow in the circuit. This makes it an ideal component for use in buck-mode DC-DC converters, voltage regulators, and other applications that require a steady current flow.
