How to Use This Calculator

Tips

  • • Air core inductors have lower inductance but higher Q factor
  • • Increasing turns increases inductance proportionally to N²
  • • Smaller coil diameter gives higher inductance
  • • Wire diameter affects DC resistance and current capacity

Important Notes

  • • Calculations assume ideal conditions
  • • Real coils have parasitic effects
  • • Temperature affects wire resistance
  • • Consider safety margins for high current applications
