LC Low / High Pass Cutoff

Calcuate the cutoff frequency for a given inductor and capacitor LPF / HPF filter by entering the values below. You can also use SI units, eg (22p, 60u, etc)

Inductor Turns Calculator

Roughly estimate the number of turns and length for an air-cored inductor based on the required inductance and former diameter. You can also use SI units, eg (22p, 60u, etc)
