Inductors are passive electronic components that store energy in a magnetic field when electrical current flows through them. They play a crucial role in various electronic circuits, serving functions such as filtering, energy storage, and voltage regulation. As technology continues to evolve, the applications of inductors have expanded significantly, making them indispensable in modern electronics. This article aims to explore the different product types that utilize inductors, highlighting their importance across various industries.
Inductance is the property of an electrical conductor that opposes changes in current. When the current flowing through an inductor changes, it induces a voltage in the opposite direction, according to Lenz's Law. This property allows inductors to store energy temporarily and release it when needed, making them essential for managing electrical energy in circuits.
Inductors consist of a coil of wire, often wound around a core material. When current passes through the coil, a magnetic field is generated around it. The strength of this magnetic field is proportional to the amount of current flowing through the coil. When the current changes, the magnetic field also changes, inducing a voltage that opposes the change in current. This behavior is what makes inductors useful in various applications, from filtering signals to storing energy.
Inductors come in various types, each suited for specific applications. The most common types include:
Air-core inductors: These inductors do not use a magnetic core, making them suitable for high-frequency applications due to their low losses.
