A fixed inductor is a passive two-terminal electrical component used to store energy in the form of magnetic fields when electrical current is applied, usually in the form of a coil. Fixed inductors are also known as chokes, reactors or coils. They are commonly used in radio frequency circuits, and are ideal for applications such as filtering, blocking, coupling, or tuning.

The DR124-120-R is a fixed inductor that is particularly suited for use in radio frequency applications such as mobile phones and wireless communication systems. This inductor has a maximum operating frequency of 15GHz and can handle up to 2.5A current. It features a high Q factor and low insertion loss.

The DR124-120-R contains a coil of wire, called a winding, when an electric current is applied to it, a magnetic field is produced. This magnetic field allows the inductor to store energy in the form of a magnetic field.
The field produced by the current causes the DR124-120-R to produce a voltage within the winding. This voltage is directly proportional to the rate of change of current, and represents the inductance of the inductor. The inductance can be varied by changing either the number of turns in the winding or the core material used.

The working principle of the DR124-120-R is based on Faraday’s Law of Electromagnetic Induction which states that the induced emf in a circuit is equal to the rate of change of the magnetic flux linked with the circuit.

When electric current is passed through the winding of the DR124-120-R, a magnetic field is produced, and as the current changes, a voltage is induced in the winding which is proportional to the rate of change in the current. This voltage is the counter emf which is generated due to the induced magnetic field. This counter emf acts as a damping force and reduces the current in the circuit. This effect is known as impedance and is expressed in ohms.

The DR124-120-R is a passive two-terminal electrical component that can be used to store and discharge energy in the form of a magnetic field. It is commonly used in radio frequency circuits, and is ideal for applications such as filtering, blocking, coupling, or tuning. It has a high Q factor and low insertion loss, making it ideal for high-frequency applications. It is also well-suited for mobile phones and other wireless communication systems.
