Fixed Inductors are essential components in electronic circuits. They create a magnetic field around its core which can be used to store energy or manage power. The most common type of fixed inductors is the FIT80-1, which offers a wide range of applications and working principles.

The FIT80-1 is a fixed inductor made of ferrite bead, a negative temperature coefficient (NTC) resistor and two fixed coils. Ferrite beads include a high resistance ceramic material which helps to reduce electrical noise and electromagnetic interference from adjacent components, but also to reduce eddy current losses. The fixed coils are designed to act as current-limiting components, reducing electromagnetic interferences and increasing the coils\' total inductive reactance. The NTC resistor is used as the secondary element in the circuit.

The FIT80-1 is typically used to increase the current flow in a given circuit and regulate the voltage level. It is a key component in power supplies design, allowing engineers to create more efficient and powerful electronic devices. By changing the parameters of the inductor, such as the number of turns and the number of coils, engineers can also optimize the FIT80-1 for applications such as audio filter, switch-mode power supplies, and motor control.

In addition, the FIT80-1 can be used to store energy when used together with a capacitor. This is done by connecting a capacitor to the fixed coils, so that an alternating current can be stored in the capacitor and gradually released from the inductor. This technique is widely used in power supplies designs and is used to increase the current flow in high-power applications such as DC-to-DC converters.

The FIT80-1 can also be used as an RF reactor or an EMI shield. It is used to create a magnetic field to shield against electromagnetic interference from nearby components, which can cause interference in the current passing through a circuit. The FIT80-1 can be tuned to provide a strong, consistent magnetic field to effectively reduce interference. This technique is especially useful in high-frequency applications such as radio-frequency (RF) circuits.

The applications and working principles of the FIT80-1 fixed inductor make it an essential component for many types of circuits. By changing the parameters of the inductor, engineers can customize its characteristics to meet the specific requirements of their design. The FIT80-1 is a powerful and versatile tool for any engineer looking to optimize their circuits’ performance.
