PA2891.321HL

Fixed inductors help store electrical energy in a magnetic field, and the PA2891.321HL inductor is no exception. It is a commercial grade fixed inductor, primarily used in switching power supplies, telecommunication systems, and other applications that need a flexible inductance range.

The PA2891.321HL consists of a ferrite core and several windings of copper wire; the core material is what determines the inductance. The core also helps reduce radiated noise, making this inductor ideal for applications where noise suppression is necessary. The surface mount design also makes it a preferred choice for maximum board utilization.

The PA2891.321HL offers excellent electrical characteristics. It has an inductance range from 0.1µH to 10.0µH and is rated for a 2.2A maximum current with an isotropically dependent resistance of 0.0055 ohms. It also has a typical saturation current of 40A and an operating temperature between -55°C and 150°C.

As previously mentioned, this inductor is primarily used in power supplies and telecommunication systems. Due to its wide inductance range and low resistance, it is also used in a variety of low voltage DC circuits. It is also used in a variety of switch-mode power supplies including DC-DC converters, AC-DC converters, and AC-AC converters. Its low profile, low noise, and high saturation characteristics make it an ideal choice for these types of applications.

The PA2891.321HL is a fixed-inductance device that serves as an energy-storing element in an electrical circuit. In essence, the inductor stores energy in the form of a magnetic field which is generated when current flows through the wire. When the inductor is placed in series with a voltage source, the magnetic field induced by the current allows the voltage to regulate itself, and the inductor thusly serves as a passive electromagnetic device.

The PA2891.321HL inductor allows for a variety of applications due to its flexible inductance range, excellent electrical characteristics, and low noise and high saturation. It is a popular choice for switching power supplies, telecommunication systems, and other low voltage DC circuits.
