Inductor Technology

Fundamentals

Inductors are passive electrical components that store energy in a magnetic field when electric current flows through them. They oppose changes in current and are fundamental components in AC circuits, filters, and energy storage systems.

Key Properties:
  • Inductance (L): Measured in Henries (H)
  • Quality Factor (Q): Ratio of reactive to resistive impedance
  • Self-Resonant Frequency: Natural resonance with parasitic capacitance
  • Current Rating: Maximum safe operating current
Applications

Inductors are used in power supplies, filters, oscillators, transformers, and energy storage systems. Understanding their behavior in AC circuits is essential for electrical engineering applications.
