## Calculating LC Resonance Capacitor

 https://ibb.co/n45Cqb How to calculate C3 Capacitor from this schematic? L2= 91uH , (T1) Push Pull Frequency = 17khz by userbg September 30, 2017

 Resonant frequency is 1/(2.pi.sqrt(LC)) where sqrt is square root and pi is, well, pi. Use simple algebra to get the value of C3 from f and L2.
