Fixed Inductors

An IHTH1125MZEB2R2M5A fixed inductor is an electrical component that stores energy in the form of electromagnetic fields. It is a passive two terminal device composed of an air core with windings of copper or another conductor around it. When an electric current is passed through the windings, an electromagnetic field is generated. The magnetic field is able to absorb energy from the current, temporarily increasing the amount of energy present in the circuit. This is known as an inductor\'s inductance, which is measured in henries.

Application Field

Fixed inductors are commonly used in signal conditioning and signal processing applications. In particular, they allow AC circuits to reject unwanted signals and adjust the phase of the output signal. In radio frequency (RF) applications, fixed inductors are used to filter signal. They can be used to construct tuned circuits for the purpose of providing frequency selective or frequency-dependent gains. In addition, they are widely used in the design of power electronics, power supplies, switching regulators, and other power management systems.

Working Principle

The working principle of a fixed inductor is based on the law of induction. When a current flows through the winding of an inductor, an electromagnetic field is established. This consequently creates a magnetic field around the inductor. The magnetic field then exerts a force on any electric current passing through it. This force actually resists the flow of current which causes a voltage difference in the device. This voltage difference is called voltage drop and is proportional to the amount of current flowing through the magnetic field.

The amount of voltage drop depends upon the inductance of the device. The greater the size and more efficient the winding of the inductor, the greater the inductance. This higher inductance is also referred to as higher reactance. A higher reactance results in a higher voltage drop which in turn reduces the total current in the circuit.

At high frequency signals, the current in an inductor may become so strong that the device cannot handle it. This is known as induction saturation. In such cases, the inductor is said to be saturated and the voltage drop becomes constant, regardless of the amount of current passing through the inductor. The saturation is the reason why fixed inductors are most commonly used in signal conditioning and radio frequency (RF) applications.
