How Inductance Products' Inductors Work
Conductive materials can be ferromagnetic or paramagnetic, while non-conductive materials are diamagnetic in nature. Because of these properties, most conductors exhibit inductance whenever the direction of the current changes or is observed to flow in the opposite direction, which is the resistance that a conducting material exhibits in response to the current flowing through it. Inductors contain conductors of this shape that increase the inductance of the device by increasing the magnetic flux, and any change in this magnetic flux may induce electromagnetic flux or voltage in the circuit.
Types of Inductors
Toroidal Inductors – These inductors have a toroidal core with a specific current carrying capacity and inductance. They are used in power circuits and they support low frequencies without affecting large inductance values. They have higher inductance per turn than other inductor types and are capable of carrying large currents. Therefore, these inductor types are used in equipment such as EMI circuits, amplifiers, switch-mode power supplies, electronic brakes and clutches, air conditioners, and medical equipment.
Ferrite Inductors - These transformers use ferrite cores, a mixture of iron oxide and magnesium oxide/zinc oxide at high temperatures. Their high resistivity, low eddy current losses, and excellent permeability make them suitable for applications such as switching circuits, noise-filtering devices, switching regulators, and industrial converters.
Surface Mount Power Inductors –These inductors are used in miniaturized power circuits such as electronic applications using AC-DC converters and DC-DC converters, graphics cards, desktops, laptops, battery-powered devices, and servers application.
Air Core Inductors - These inductors have a non-magnetic core, the coil is wound around plastic, or the coil is self-supporting. Therefore, these types of inductors have no core losses, making them non-saturating. Furthermore, they ensure reliable performance at high frequencies, making them easy to use in radio and microwave frequency applications such as signal transmission systems, air navigation systems, land mobile radio systems, marine communication equipment, and radar equipment.
