InductorCalc

Designing your own inductor or coil?
InductorCalc makes it quick and easy to get the key parameters you need.

Enter your coil’s physical dimensions — number of turns, length, and diameter — and instantly calculate:
• Inductance (L) in a range of SI units
• Q-factor at your chosen operating frequency
• Total wire length needed for the winding
• DC resistance based on your wire’s Ω/m value

Simply fill in the fields, tap Calculate, and let the app do the math.
Perfect for electronics hobbyists, students, and anyone building custom inductors.
