The Inductor Q Factor Calculator evaluates the quality factor (Q) of an inductor, describing the ratio between stored and dissipated energy. A high Q indicates low energy loss relative to stored energy.

Inputs

Outputs

EXAMPLE:

  • INPUTS:

    • Frequency = 100 MHz
    • Inductance = 10 nH
    • Internal Resistance = 0.5 Ohm

  • OUTPUT:

    • Q factor of inductor = 12.56

Benefits/Applications

  • Improves resonant circuits: High Q inductors lead to narrower bandwidth and better selectivity.
  • Essential for filters and oscillators: Performance hinges on a stable, predictable Q.
  • Predicts inductor behavior: Helps in choosing components for power and RF electronics.

Summary:

This tool computes the quality factor of an inductor based on its inductance, resistance and frequency, guiding component choice for optimized performance.
