Fixed Inductors

Inductors are electronic components with the primary purpose of providing inductance. Inductors are used in a broad range of circuits, particularly those involving signals with low frequencies. A fixed inductor is an inductor with a specified inductance that deviates by no more than a given amount from its nominal value, i.e., the value specified by the manufacturer. Fixed inductors are usually rated for a specified DC current at a given temperature and can handle both AC and DC current. Among the most common types of fixed inductors are the wire-wound, ferrite bead, and axial versions.

1331R-123K Fixed Inductor Field and Working Principles

The 1331R-123K fixed inductor is a typical wire-wound version. It is composed of a metal core wound with insulated copper wire, with a plastic cover to protect the wires. This inductor is usually used in applications requiring up to four amps of current, with a maximum of five amps at room temperature. The 1331R-123K fixed inductor can operate at a variety of frequencies, from DC to 10 MHz.

The working principle of the 1331R-123K fixed inductor is based on the electromagnetic properties of inductors. When a changing electrical current is applied to the inductor, it stores energy in a magnetic field and then releases it as a voltage when the current is removed. The amount of voltage released is proportional to the inductance and the rate of change of the current that is stored. The total amount of energy stored is determined by the amount of inductance.

The 1331R-123K fixed inductor can be used in a variety of applications. One common application is in switching power supplies, which use inductors to control the current flow and reduce the effects of noise. They can also be used for suppressing unwanted EMF and noise generated by high-speed digital circuits. Additionally, inductors can act as flyback diodes for protecting components from reverse voltage.

The 1331R-123K fixed inductor offers high-frequency operation and is suitable for use at high temperatures. It is also UL recognized for use in applications up to 105°C. The device is available in a variety of enclosures, including through-hole, surface-mount, and chassis mount versions. The through-hole and surface-mount versions are epoxy encapsulated and molded for improved reliability and environmental protection.

The 1331R-123K fixed inductor is a reliable and versatile component that can be used in a wide range of applications. It offers a high inductance with a low DC resistance, making it a suitable choice for circuits with low impedance requirements. Additionally, this inductor is designed to withstand temperatures up to 105°C, making it suitable for use in high-temperature applications.
