Fixed Inductors

A fixed inductor (or coil) is an electrical device consisting of a length of wire or foil wound in a spiral around an insulated core. When the two ends of the coil are connected to a voltage source, a current flows through the coil and produces a magnetic field. This magnetic field induces an electric field which, in turn, produces a current.The UP0.4SC-2R2-R is a type of fixed inductor used in a variety of applications such as radio frequency (RF) circuits, audio circuits, surge protection, and power supplies. This particular fixed inductor has a inductance range from 0.2 uH to 10 mH.There are two main types of fixed inductors: air-core and ferromagnetic core. The UP0.4SC-2R2-R is an air-core inductor which means it has a length of wire wound around an air-filled central core. The inductance of an air-core inductor is defined by its geometry and winding diameter. The UP0.4SC-2R2-R has a winding diameter of 0.4mm and a length of 10mm.The working principle of a fixed inductor is based on Faraday’s law of induction. When a current flows through the coil, it produces a magnetic field which induces an electric field. This electric field then produces a current in the opposite direction, thus setting up a feedback loop in the circuit. This feedback loop is responsible for allowing the current to continue flowing in a self-sustaining manner.In many applications, the UP0.4SC-2R2-R fixed inductor is used to filter frequencies or reduce background noise in an audio signal. It can also be used as part of an antenna circuit or a voltage regulator. The UP0.4SC-2R2-R fixed inductor is also used in radio frequency (RF) circuits to inductively couple to an antenna, amplify signals, or tune circuits.The UP0.4SC-2R2-R fixed inductor can also be used in surge protection circuits as part of an over-voltage protection device. It protects sensitive electronic devices from being damaged due to over-voltage by quickly diverting any excess current away from them. The UP0.4SC-2R2-R can also be used in power supply circuits to increase the voltage and current supplied to the load.The UP0.4SC-2R2-R fixed inductor is a versatile and reliable component that can be used in a variety of applications. Its low inductance range, high quality construction, and compact size make it a great choice for many circuit designs. As such, it is an essential component for any electronics engineer.
