Fixed Inductors

Inductors are passive electrical components used to provide inductance in a circuit. Inductors are typically made from a wire wound around a core made of ferrite, iron, air, or a combination of these materials. Inductors store energy in the form of a magnetic field. This energy can be released when the current through the inductor changes. Fixed inductors are inductors that are not adjustable and their inductance is determined by their physical construction.

The 2256-331J is a fixed inductor with an inductance of 33 µH. It is made from a ferrite core surrounded by a copper wire winding. The 2256-331J is a 900 mA rated inductor, meaning it can handle up to 900 mA of continuous current. It has a low 0.008 ohm DCR and a high 3000mA core saturation current.

Application Field and Working Principle

The 2256-331J fixed inductor is primarily used in switching power supplies, high-frequency converters, and other power circuits. It is also used in low frequency transformer applications where an axial inductor is required. The 2256-331J is rated for up to 1500V of DC voltage.

The working principle of the 2256-331J is quite simple. Current flowing through the copper windings creates a magnetic field that induces a voltage in the windings. This voltage is inversely proportional to the rate of change of current, thus creating an inductance effect. The magnetic field can be concentrated by using a ferrite core, resulting in a higher inductance value. The DCR is also very low, meaning less energy is dissipated in the form of heat.

The 2256-331J fixed inductor is a reliable and efficient component ideal for high-frequency and power applications. It can handle up to 900mA of current and has a low 0.008 ohm DCR. Its ferrite core helps to concentrate the magnetic field, resulting in a higher inductance value. Additionally, the high saturation current ensures that the inductor does not experience significant voltage drops when large amounts of current are passed through it.

In summary, the 2256-331J is a reliable and efficient fixed inductor ideal for high-frequency and power applications. It has a low DCR, a high saturation current, and a 3000mA rated core. Its design helps to concentrate the magnetic field, resulting in a higher inductance value and better performance in high-frequency applications. The 2256-331J is available in both through-hole and surface mount packages and is a reliable component for any power or high-frequency application.
