Fixed Inductors

Fixed inductors, also known as choke coils, are passive electronic components used to store energy due to the inductive reactance of an electric current. The ISC1812RX100K is a fixed inductor that is typically used as a noise suppression device, or as part of a dc/dc converter, or as a broadband matching device. In this article, we will discuss the application field and working principle of the ISC1812RX100K.

Application Field

The ISC1812RX100K is primarily used for broadband UHF signal filtering or impedance matching. It can also be used for other RF applications, such as in-line and hanging type applications. The inductor is also used for power line EMI suppression, and as a noise blanking capacitor for noise suppression. The inductors are also used for temperature stability, noise immunity, VHF/UHF signal shielding, and RFI suppression.

Working Principle

The ISC1812RX100K is an air-core, fixed inductor. As the name suggests, it is composed of an air core, a winding, and a wire form. The air core is the non-conducting part of the inductor, and is usually made of a suitable material, such as plastic, ceramic, or metal. The coil is typically made up of several concentric coils, or layers of insulation material, and is wound with insulated copper wire. The wire form is the connection between the winding and the external load of the inductor.

When a current flows through the inductor, an inductive reactance is created, which causes an increase in the voltage across the inductor. This is referred to as a “back-emf” signal, and is capable of producing a capacitor-like action. This is because the increasing voltage across the inductor carries energy to and from the inductor, creating a “push-pull” effect. The result is an increase in the inductance of the inductor.

The inductance of the ISC1812RX100K determines the amount of signal it can carry, and is what makes it useful for broadband UHF signal filtering or impedance matching. This is because the inductance is proportional to the amount of current passing through the inductor, and higher levels of current will result in higher levels of inductance. The inductance can also be adjusted by altering the number of windings on the core. The ISC1812RX100K is also temperature-stable, which allows it to maintain a consistent inductance over a wide range of temperatures.

The ISC1812RX100K is an essential component for UHF signal filtering and applications requiring high levels of signal transmission. It can also be used for other DC/DC conversion or broadband matching applications. It is a reliable component due to its high level of winding accuracy, low radiated noise, and temperature stability.
