Fixed Inductors

Inductors are electronic components consisting of a coil of copper wire with a core of magnetic material such as iron or soft ferrite. A typical inductor is comprised of a plastic enclosure with two metal terminals for connecting to a circuit. An inductor allows electric current to pass through it but resists changes in the current, creating an energy storage effect. Fixed or fixed-value inductors are designed with a specific resistance value that does not change over time as they are not designed to be adjustable.The RLF7030T-2R2M5R4 is an example of a fixed inductor that is used for a variety of applications in electronic circuits. It is a miniature surface mount SMD inductor with an inductance of 2.2 mH (milli-Henries). It has an operating temperature range between -55°C and +125°C and a rated current up to 15A.These fixed inductors are used in a number of devices and applications. For example, they are found in power supplies to control the flow of current in the circuit. They are also used in audio systems as bass-boost circuits, RF amplifiers, and switching circuits. They are also used as sensing components in proximity switches and current transformers.The working principle of fixed inductors is based on Faraday’s law of induction. As the current through the coil increases, a magnetic field is created around the core, creating a back-EMF or self-induced voltage. This back-EMF is proportional to the rate of change of the current within the coil.The back-EMF opposes the current flow and produces a certain amount of “self-induced resistance” in the coil. This resistance, called inductance, is the property of fixed inductors that allows them to store energy when a current flow is increased or decreased. The inductance of a fixed inductor will always remain a constant based on its design.Fixed inductors are widely used in many different electronic applications due to their stability, compact design, and cost effectiveness. Their stability ensures reliable performance in a wide range of temperatures and environments. Their small size also helps reduce weight and footprint without compromising on performance. And due to their low cost, they are often preferred for applications involving low-cost electronics.The RLF7030T-2R2M5R4 is a great example of a fixed inductor that offers a great balance of performance, reliability, and cost. It is an ideal choice for a range of applications from power supplies to audio systems, RF amplifiers, switching circuits, and more.
