3090R-331J

Fixed inductors are components that store energy by inducing a magnetic field around them. These inductors differ from other components, such as capacitors, in that they are designed to maintain a constant value of inductance and do not change their impedance as frequency and temperature vary. Common applications for fixed inductors include radio frequency (RF) communications, audio filtering, magnetic shielding and rectifiers. The 3090R-331J is a small surface-mount inductor with a rated inductance in the range of 0.47 to 1.00 μH, making it suitable for use in RF communications, as well as audio circuit designs.

Fixed inductors consist of a core of ferromagnetic material, such as iron, surrounded by a coil of insulated wire. They are usually also enclosed in a casing to protect them from physical damage. The core of the 3090R-331J is made of ferrite, while the wire is composed of AWG#30 copper with an insulation rating of 600 V. This allows it to withstand a relatively high voltage level of up to 900V.

When a current flows through the inductor, it generates a magnetic field, which inducts an electric field in the opposing direction. This phenomenon is known as inductance and is measured in Henrys (H). This field also contains a certain amount of energy, and this is known as inductive reactance. The 3090R-331J\'s inductance is 0.47 to 1.00 μH, with an inductive reactance of 37 Ohms.

Fixed inductors such as the 3090R-331J have a wide range of applications. In RF communications, they are used to create an isotropic antenna pattern and improve the performance of an antenna system. They are also used to reduce interference from external sources, which enter the system and cause signal distortion. In audio filtering, they are used to block or reduce unwanted frequencies, allowing for better sound quality.

Fixed inductors are also commonly used in rectifier circuits, where they help to regulate the flow of both current and voltage. They are also used in magnetic shielding, which helps to prevent conducted or radiated interference from external sources. Finally, they are used in high-frequency power supplies, where they can help to reduce power dissipation.

The 3090R-331J is a small surface-mount inductor designed for use in a variety of applications. Its rated inductance is in the range of 0.47 to 1.00 μH, which makes it suitable for use in RF communications, audio filtering, magnetic shielding and rectifier circuits. Its ferrite core and AWG#30 copper wire with a 600V insulation rating give it a relatively high voltage rating, making it a reliable and versatile choice for a wide range of applications.
