Fixed InductorsInductors are electrical components which are used in a wide variety of electronic circuits. Inductors create an inductive field when a current is passed through them. This inductive field can then store energy in the form of magnetic flux. Fixed inductors are commonly used in applications where the inductance value must remain constant. One such fixed inductor is the 2890R-38H. This article will discuss the application field and the working principle of the 2890R-38HThe 2890R-38H fixed inductor is primarily used in radio frequency (RF) applications. It is also commonly used in signal processing circuits such as filter networks, amplifiers, and similar circuits. The 2890R-38H is designed to provide a stable, consistent inductive field and is usually used in circuits that require an accurate and repeatable inductance.The 2890R-38H is a medium-sized inductor with a diameter of approximately 20mm and a height of 27mm. It has two lead pins, one of which is connected to a ground plane. The inductor is constructed of a PVC coil with a ferrite core. The inductance of the 2890R-38H is typically specified as 33-37uH.The working principle of the 2890R-38H is based on Faraday’s law of induction. When a current is passed through the inductor, it creates a magnetic field with a strength proportional to the current. This magnetic field then induces a voltage in the coil of the inductor which is proportional to the rate of change of current. This induced voltage creates an opposing current in the coil which results in the inductor storing energy.The 2890R-38H is a versatile fixed inductor that can be used in many different types of circuits. Its small size and high inductance make it an ideal choice for many RF applications. Its consistent and accurate inductance also makes it a reliable choice for filter networks and signal processing circuits. When used in these types of circuits, the 2890R-38H can provide a stable and repeatable inductance value which can improve the performance of the circuit.
