What is an Inductor?
An inductor is a passive electronic component that stores energy in a magnetic field when current flows through it. It's essentially a coil of wire, often wound around a magnetic core.
Formulas
Energy: E = Ā½ Ć L Ć IĀ²
Inductive Reactance: XL = 2Ļ Ć f Ć L
- E: Energy stored (Joules)
- L: Inductance (Henries)
- I: Current through inductor (Amperes)
- XL: Inductive reactance (Ohms)
- f: Frequency (Hertz)
Common Applications
- Power Supplies: Switching regulators, DC-DC converters
- Filters: Low-pass, high-pass, and band-pass filters
- RF Circuits: Tuning circuits, impedance matching
- Energy Storage: Flyback converters, boost converters
- EMI Suppression: Reducing electromagnetic interference
Key Characteristics
- Opposes changes in current (like capacitors oppose voltage changes)
- Reactance increases with frequency
- Acts as short circuit at DC, open circuit at high frequencies
- Can generate high voltage spikes when current is interrupted
