Fixed Inductors
Fixed inductors (0819R-20Fs) are specialized electronic components that primarily function to regulate the flow of current. They are primarily used in direct current (DC) circuits but can also be used for AC applications up to certain frequencies. Their design and functionality is based on the principle of inductance, which states that an electric current creates a magnetic field that then in turn induces an electromotive force in a nearby conductor. This force opposes the current\'s original direction and, in turn, acts to regulate the current\'s flow and intensity. Fixed inductors use this principle to shape the properties of the current, allowing for stability and precision in certain applications.
As the name implies, fixed inductors are physically characterized by their fixed values of inductance, which is measured in a unit known as the Henry (H). Based on this value, these devices can have a wide range of applications from low frequency signal processing to RF energy transmission. Fixed inductors range in size from small to medium and may come in several electrical configurations such as axial, smd, or shield designs.
Fixed inductors, such as the 0819R-20F, work based on the principle of unitary impedance. This states that the impedance of the device is defined as the ratio of the voltage to the electric current passing through it, whereas the power passing through is equal to the power applied. Thus, the voltage across the inductor is equal to its inductance multiplied by the current passing through it. As such, by controlling the voltage across the inductor, the current can be regulated, allowing for precision and control of the passage of electric current.
The voltage of the 0819R-20F fixed inductor is typically adjustable, allowing for better control of the current flow. Some of these devices come with a needled type of adjustment mechanism to allow for one-time fine tuning, primarily for voltage-controlled applications. In order to adjust the non-adjustable types of fixed inductors, bias voltage can be applied as a method for transposing the voltage across the device, thereby controlling the current passing through it.
Fixed inductors are used in a variety of applications such as high frequency signal processing, harmonic dampening, power supplies, battery management systems, and more. They play an important role in the construction of many electronic devices, ensuring stable and precise electric current flow. The 0819R-20F fixed inductors in particular are known for their high capacitance and efficient energy transfer, making them ideal for high frequency applications such as RF and power conversion.
