Fixed Inductors

Fixed inductors are components that store energy in the form of magnetic field. They are mostly used in power supply designs and are available in a wide variety of ratings. The 2890-38G series of fixed inductors are specifically designed for high performance applicationsand offer exceptional performance in terms of inductance rating, low voltage drop, current rating, and operating temperature range.

The 2890-38G is constructed with a core of silicon steel and winding that employs a multilayer arrangement. This configuration enhances the performance of the inductor and allows it to handle higher current levels. The inductance rating of the device is varied by adjusting the number of windings in the core. Additionally, the current rating of the device is also adjusted by altering the number of winding layers.

The 2890-38G series of fixed inductors are particularly suited for applications in power supply designs. They are typically used in power supplies to help distribute power throughout the components in a system. The inductors act as a filter, blocking high frequency interfering signals and ensuring that only the desired signal passes through. Additionally, they help prevent power fluctuations, ensure output current is consistent, reduce power dissipation, and enhance performance. As a result, they are a key component in optimizing power supplies.

The working principle of the 2890-38G inductors is based on Faraday’s law of induction. This states that when a magnetic field is applied to a conducting material, an electric current is induced in the conductor. The inductor is designed to utilize this effect in order to store energy in the form of a magnetic field. When a current is passed through the winding of the inductor, a magnetic field is created in the core which stores the energy. When the current is reduced or stopped, the stored energy is released from the core.

In conclusion, the 2890-38G series of fixed inductors are an ideal choice for power supply designs. This type of inductor offers a range of performance benefits such as enhanced inductance rating, low voltage drop, high current rating, and wide operating temperature range. Moreover, their working principle is based on Faraday’s law of induction and they are capable of storing energy in the form of a magnetic field.
