Fixed Inductors, also known as Coil, are widely used in various electronic circuits for capacitive, filtering, damping, oscillating, coupling, shaping and other applications. 1025R-92J is a type of Fixed Inductor, which is often used in the circuit of frequency adjustment in the microwave circuit.

The working principle of 1025R-92J fixed inductor is mainly based on Faraday’s law of electromagnetic induction. That is, when a magnetic conductor passes through a magnetic field, a current is induced in the conductor due to the effect of the magnetic field. According to the Faraday law, when the current changes, the induced voltage also changes, and the voltage is proportional to the rate of change of the current, which is called the eddy current. According to Lenz\'s law, when the current changes, the direction of the induced voltage is the opposite direction of the current.

1025R-92J fixed inductors are mainly used in microwave circuits. The frequency adjustment circuit is the main application of this type of inductor. A frequency adjustment circuit is a relatively important circuit in a microwave circuit system. In the frequency adjustment circuit, it is mainly completed by the 1025R-92J fixed inductors for frequency adjustment and filter functions. The 1025R-92J fixed inductor is composed of a single-winding wire wound on a single-core type dielectric. The winding wire is coated with a vacuum-sealed enamel that can contact the dielectric medium. The process of its work is mainly that when the current flows through the winding wire, an electro-magnetic field will be formed around the winding. The magnetic field changes due to changes in the current of the winding, so that the induced current is generated in the electric core, which affects the frequency adjustment.

The 1025R-92J Fixed Inductor also has some limitations. First, its self-resistance is too great, which will lead to the increase of power consumption. Second, the difference of temperature and relative humidity will cause the increase of the inductance value, thus affecting the reliability of the frequency adjustment. Third, because the winding has a certain distributed capacitance, it will cause the impedance characteristic at the resonance frequency to vary widely, so that the adjustment frequency is unstable.

In conclusion, 1025R-92J Fixed Inductor is mainly used in the frequency adjustment circuit of the microwave circuit due to its working principle. However, its working performance and stability are limited to certain degree. Therefore, correct selection, operation and maintenance of this type of inductor and circuit is particularly important.
