SD3110-820-R

Fixed Inductors

Inductors, also known as coils, are electrical components that store energy using a magnetic field. The SD3110-820-R is a type of fixed inductor, made up of copper windings around a ferrite core. This component is of a surface mount architecture and has an operating temperature range of -40 to +85 °C.Fixed inductors are important components in power applications, such as AC/DC rectifiers, power supplies, switch-mode power supplies, and motor controls. The SD3110-820-R is commonly used in these kinds of applications due to its excellent electrical characteristics, which include maximum current of 2.2 Amps and inductance of 28.5 microHenries at 1.4GHz. It also has a saturation current of 1.51 Amps (TYP), low thermal resistance, and typical voltage rating of 250 Volts AC.

Application field

The main application fields of the SD3110-820-R are telecom power systems, power conditioning systems, and other power-related systems. This component is suitable for modern power designs due to its excellent electrical characteristics.In telecom power systems, it can be used to reduce high-frequency harmonics, filter out any high-frequency noise, and smooth out dC power. This component is also ideal for use in power conditioning systems due to its high-frequency performance and low self-heating. It can also be used as a current source and current limiter in motor control systems.The SD3110-820-R is also capable of providing a low-noise alternative to conventional wire-wound inductors. This feature makes it suitable to be used in a variety of audio applications. It can be used in audio crossover networks, power amplifiers, and public address systems.

Working principle

The working principle of the SD3110-820-R is based on the Faraday\'s law of induction. This law states that the magnitude of the induced electromotive force (emf) in an electrical circuit is directly proportional to the rate of change of magnetic flux in that circuit. This can be expressed as,_E = -dΦ/dtWhere, E represents the induced emf, dΦ represents the rate of change of the magnetic flux, and t represents the time taken.When current passes through the windings of the SD3110-820-R, the windings create a magnetic field. This magnetic field changes with time, and as per Faraday\'s law, an induced voltage is created. This induced voltage opposes the applied voltage, resulting in a lower output voltage. This phenomenon is known as inductive reactance.The SD3110-820-R also has a high self-resonance frequency. This means that when oscillating input signals are applied to its windings, the resonance frequency is high enough to avoid unnecessary power loss due to AC/DC conversion.
