Fixed InductorsFixed inductors are electrical components used to introduce inductance into an electrical circuit. They come in different sizes and configurations, but the most common are made of two pieces of coiled metal called windings. The windings are connected to two terminals, and a current passing through the inductor will induce a magnetic field. This field can be used to store energy as well as for filtering or frequency conversion purposes.The 105R-822J is part of the family of fixed inductors. It is a high power variable inductor, which means that the inductance can be changed while the inductor is in operation. This feature gives engineers a lot of control when designing a circuit that requires precise tuning or signal filtering.The 105R-822J is made up of two windings, each with an inductance of 0.1uH. This allows engineers to change the inductance by connecting the two windings in series or parallel. By changing the connection, engineers can have an inductance that ranges from 0.2uH to 0.5uH. The inductor also has a wide temperature range, ranging from -40°C to 150°C.This fixed inductor is most commonly used in operational amplifiers, signal filters, oscillator circuits, amplifier stages, and in various electromagnetic applications. The variable inductance of the 105R-822J makes it easy to fine-tune a frequency signal. This allows engineers to create high-precision filters that can be used to reduce noise or unwanted signals in an electrical circuit.The working principle of the 105R-822J is based on Faraday\'s law. When a current passes through the inductor, a magnetic field is created. This magnetic field is then used to convert electrical energy into magnetic energy, which is then stored in the inductor until the current is cut off. When the current stops, the energy stored in the magnetic field is released back to the circuit. This makes the 105R-822J an efficient and reliable way to store energy.The 105R-822J is a commonly used and reliable component in many electrical circuits. Its adjustable inductance allows engineers to design signals that are precise and efficient. The ability to store energy using this fixed inductor makes it an excellent choice for noise reduction or signal frequency control purposes.
