Fixed Inductors are among the essential components found in any electrical or electronic device. They’re mostly known for their ability to store electrical energy in a form of an electromagnetic field. In a typical application they can appear in such forms as a coil or a choke of a power supply circuit, radio transmitter, a loudspeaker or a line filter. They are capable of blocking the DC current while allowing the AC current to pass.

Such inductors also demonstrate the unique characteristic of having a constant inductance, which gives them their classification as ‘Fixed Inductors’ – a capacitance which is not affected by changes in frequency, voltage, or current, except for the resulting non-linearity due to saturation of core materials.

One specific type of Fixed Inductors are the 5022R-104F. This type is designed for high-stability operations, and can be used for applications with a wide range of temperatures. The 5022R-104F’s is a radial-leaded inductor of 10.2mm x 4.0mm size, with 4.2A current and 10uH inductance. This type of inductor has particularly good performance characteristics.

The primary application of the 5022R-104F is usually in the DC power blocking circuits, due to its high DC current capability. This Fixed Inductor can also be used in power lines where current reduction is necessary, or for suppressing high frequency noise. The majority of inductor use will be found, however, in the power-supply and battery charging circuits.

The working principle of the 5022R-104F is reasonably simple. This type of inductor works by creating an electromagnetic field when current is passed. This field in turn will induce a current in the opposite direction, opposed to and working against the original current. This method of working is known as a ‘reactive force’, as it both resists and creates a reverse current. The material of the inductor core will serve to protect it from the losses caused by the original current, while storing the energy in the electromagnetic field.

The stored energy then follows the original current and is released only when the original current is reduced or stopped. The concept of ‘inductance’ is an important factor in understanding the working principle of a 5022R-104F Fixed Inductor. This allows it to intercept and store current, which when discharged later will produce a force proportional to its inductance value.

Therefore, the 5022R-104F type of Fixed Inductor is known in engineering for its ability to resist changes of current or voltage caused by a change in the frequency, while still allowing AC to pass, thus contributing to high stability in any number of uses where DC currents must be blocked.
