It'a REALTIME ONLINE calculator!
Out targets are Hardware, pcb, system engineer
You may use metric Prefixies(like k, m,u,n,p,...).
This is a calculator for via inductance, parasitic capacitance and circumference.
Inductive and capacitive components are also generated in through-hole vias for pattern wiring.
The circumference of the via should be used as a guide to how much pattern width the via corresponds to.
