Fixed inductors, such as the 73F103AF-RC, are simple components with a single, direct purpose—to store energy in a magnetic field. Designed to prevent the magnetic field from discharging too rapidly, they slow the alternating current waveform down, which is known as inductive dampening. By slowing it down, the inductor mitigates transient voltage spikes, which can damage electronic components or the circuit as a whole.

Whether a traditional coil inductor or a more advanced self-shielding type, the 73F103AF-RC is able to effectively limit current to predetermined levels in many applications. Often found in AC/DC power supplies, filters, and regulators, this inductor helps stabilize circuits by releasing the stored energy in a desired manner. Additionally, certain types of inductors can also be used as energy boosters, increasing the current signals and values up to a specified level.

The 73F103AF-RC’s design includes a ferromagnetic core with a wire wound tightly around it. As current flows through the wire, it induces a magnetic field in the core, which stores the energy. To enhance inductance and store more energy, the closed loop area where the wire and core meet can be increased. By increasing this area, less current is flowing through each winding, so more turns are needed to maintain the desired inductance.

In order to ensure energy is released slowly, an air gap may be placed in the core. The gap prevents a complete, short circuiting loop that would cause an instantaneous release of all stored energy. Instead, it functions as a resistance between the windings, causing the current to release slowly and persist for a longer period of time. When energy is completely dissipated and the magnetic field fully discharged, the inductor is known as a ‘saturable’ inductor.

Despite its simple purpose, the 73F103AF-RC plays an important role in a variety of electrical and electronic applications. By controlling the speed of current and amplifying signal power, it helps protect vital components and increases the efficiency of many systems.
