Fixed Inductors: 2890-39K Application Field and Working Principle

Fixed inductors are essential electronic components used in many circuits to store energy in the form of inductance and to control the current flow. The type 2890-39K Fixed Inductor is one of the most commonly used types of inductors in the electronics industry. This paper provides an overview of the 2890-39K Fixed Inductor, its applications, and its working principle.The 2890-39K Fixed Inductor is a leaded radial-air core component. The part number is 2890-39K and the package size is 26.5mm x 20mm x 15.7mm. This type of fixed inductor has a rated voltage of 25V and a rated temperature range of -40°C to +125°C.The 2890-39K Fixed Inductor has a variety of applications. It is widely used in switch-mode power supplies, regulators, frequency synthesizers, filters, storage systems, amplifiers, motor drives, and computers. It is also found in consumer electronics such as digital cameras, cell phones, and GPS systems.The 2890-39K Fixed Inductor works by storing energy in the form of an electromotive force (EMF), generated by current passing through its coil. The EMF is caused by a change in magnetic flux, which is the flux that passes through the coil when a current is applied to it. As the current is passed through the coil, it induces a voltage, which is then stored in the inductor. Thus, when the current is removed, the inductor releases the energy previously stored in its electrons.The inductance of the 2890-39K Fixed Inductor is determined by the number of turns of the coil, the diameter of the coil, the length of the coil, and the core material. It is important to note that the inductance of the inductor increases as the number of turns increases and as the diameter decreases. The core material also contributes to the inductance as different materials have different permeabilities.The 2890-39K Fixed Inductor is a reliable, energy efficient, and cost effective solution for a variety of applications. It offers impressive performance in a broad range of temperatures and voltages. This type of fixed inductor is available in a variety of sizes, and can be used in a wide variety of applications.In conclusion, the 2890-39K Fixed Inductor is a versatile and reliable solution for many applications. It works by storing energy in the form of an induced EMF, and its inductance is determined by the number of turns, the coil diameter, the coil length, and the core material. This type of fixed inductor is widely used in switch-mode power supplies, regulators, frequency synthesizers, filters, storage systems, amplifiers, motor drives, and computers. It is inexpensive, reliable, and energy efficient, making it a popular choice in many industries.
