Fixed Inductors

Fixed inductors, also known as chokes or coils, are passive components in an electrical network that transfer electrical energy from one circuit to another. The name comes from their ability to store energy temporarily and release it at a later point in time. Fixed inductors are often used in communication systems, such as television and radio broadcast, for their ability to block high frequency noise. They come in both small surface-mount and large through-hole packages.

CTX03-12757 Application Field and Working Principle

CTX03-12757 is a fixed inductor designed for high frequency applications between 0.01 MHz and 6 GHz. It consists of an air-core coil with an inductance value of 1.4 μH and an impedance of 50 ohms. The inductor is suitable for use in antenna matching networks, filters, and high frequency clock oscillators. CTX03-12757 can be used in both single-ended and differential configurations.

The working principle of a fixed inductor is based on the principle of induction. When two conductive elements are separated, current flowing through one element will cause a change in the magnetic field of the other element. This will in turn induce a small voltage, known as the EMF, at the other element.

In the case of CTX03-12757, a current flowing in a coil of wire will create a magnetic field around the wire, and that magnetic field in turn will induce an EMF in any other nearby coils. The strength of this induced EMF is dependent on the number of turns in the coil, the current, and the length of wire. Since the voltage produced by the coil is directly proportional to the current, this can be used to limit current in certain applications.

Another way to make use of the inductance of a fixed inductor is to use the coil as an impedance matching element. This is necessary in high frequency applications, such as in RF antennas, in order to increase the amount of power transferred from one circuit to another. This is typically done by increasing the coil’s inductance value, which will reduce the frequency of the signal, thus allowing more power to be transferred.

In conclusion, CTX03-12757 is a fixed inductor suitable for high frequency applications between 0.01 MHz and 6 GHz, and can be used in both single-ended and differential configurations. The inductor works by creating a magnetic field around the wire, inducing an EMF in nearby coils. Additionally, the coil can be used as an impedance matching element to increase the power transferred from one circuit to another.
