Fixed Inductors
Fixed Inductors, also known as chokes, are passive electronic components that store energy in the form of magnetic fields. They consist of a coil of insulated wire wrapped around a core of ferromagnetic material. Through their coil-core combination, they transform electrical energy into magnetic energy and vice versa. SP1210R-392G is one of the many fixed inductors manufactured worldwide. It has applications in various electronic circuits such as power supplies, signal processing, radios, amplifiers, and oscillators.The SP1210R-392G is a small, radial-leaded surface-mount inductor. Its highly efficient magnetics ensure a wide operational temperature range and low DC resistance for smoother power delivery to components. It operates at rated current of 7.8A with -40 to +125¡ãC temperature range. It has an inductance of 3.9uH and a 0.077 ohm DC resistance. It also has a rated maximum current of 10.0A. The construction of this fixed inductor is provided by a reliable ferrite core material. It has a 0.32¡Ñ 0.12-inch dimension and a height of 0.16 inchs. This is a RoHS compliant inductor, which means it is free of lead, cadmium, and other hazardous substances.This fixed inductor has a magnetic field buildup before releasing it. It works on the principle of Faraday\'s Law of Induction that states that when the magnetic field around a conductor changes, a voltage is induced in that conductor. When electric charges move through a conductor, a magnetic field builds up around a coil, creating an electromagnet. This inductor follows the same principle, as it is made up of a coil of insulated wire wrapped around a ferrite core. When electric current is allowed to flow through the coil, the coil creates a magnetic field that stores energy. When the current passes through the inductor, it produces a voltage on the opposite side of the conductor, inducing a flow of electrical current through the coil. Additionally, the size of the magnetic field depends on the number of turns in the coil, meaning the amount of energy is increased when larger coils are used.This fixed inductor has applications in various electronic circuits and devices. Its low DC resistance and wide temperature range make it suitable for a range of power supplies. It can be used in DC-DC converters, transformers, buck converters, and other switching power supplies. It can also be used in signal processing applications, such as signal generators, amplifiers, and radio receivers. It is also often used in oscillators, timers, and frequency faders. These inductors are often used in audio circuits, in which they can filter out unwanted noise or eliminate crosstalk. Additionally, this inductor can be found in digital circuits, as they can help maintain a constant frequency and prevent overheating. The SP1210R-392G is an efficient and reliable fixed inductor designed for use in a variety of electronic circuits. Its wide temperature range, high rated current, low DC resistance, and high magnetics efficiency make it a reliable and cost-efficient choice for many applications. Additionally, its small size makes it ideal for space-sensitive devices and circuits.
