Fixed Inductors - IRF46ER272K Application Field and Working Principle Inductors are components used in circuitry to interact with electric circuits. They are made of a wire and a plastic core, and they are used to oppose a change in AC or DC current. Fixed inductors are designed to provide a predetermined inductance and have an output frequency that is stable over time. The IRF46ER272K is a fixed power inductor designed for the high frequency range of up to 3.2GHz.Application Field The IRF46ER272K has a versatile application field and is suitable for use in power supplies, DC/DC converters, pulse-width modulation (PWM) circuits, and as an RF low-pass filter. The inductance range of this particular component is from 2.7 to 6.8uH, with an impedance frequency range from 0.1 to 3.2GHz and a maximum current rating of up to 8A. Additionally, this component features an anti-corrosive construction and is designed for temperatures up to 180°C. Applications of this component vary from Ni-Cd, Ni-MH and Li-Ion battery chargers, wireless power transfer power supplies, solar-powered products, LED drivers, and other power management systems.Working Principle The IRF46ER272K fixed power inductor functions by relying on Ohm’s law (V=IR). Electrons traveling through the inductor create an inductive force, generating a voltage, or self-induced voltage, whose magnitude is a function of the inductance, the rate at which the current is changing, and the total current in the circuit. The power inductor stores energy inside its core, and as the current decays, the inductor releases its energy to power a circuit, and this is how it fulfills its purpose. Fixed power inductors can also protect a circuit from voltage spikes by resisting sudden changes in current. The energy stored in the inductor blocks the voltage spike, thus preventing damage to the circuit. The IRF46ER272K is designed to handle high currents and to withstand harsh environmental conditions. Other features of this component include its reduced size and use of environmentally friendly materials. The IRF46ER272K has a small size of 5.7 x 3.2mm, meaning it can fit into space-constrained applications. It is also lead-free and halogen-free, making it environmentally friendly. Conclusion The IRF46ER272K is a fixed power inductor designed for wireless power transfer power supplies, Ni-Cd, Ni-MH and Li-Ion battery chargers, solar-powered products, LED drivers, and other power management systems. This component operates by relying on Ohm’s law for current flow, and its inductive force generates a voltage, whose magnitude is a function of the inductance, the rate at which the current is changing, and the total current in the circuit. Additionally, its small size and environmentally friendly material make this component a great choice for many applications.
