Analysis of Resonance Frequency and Performance of 560R Coils

Utilizing a setup with a 560R coil, a function generator, and an oscilloscope, the resonance frequency was examined at 6KHz. Peak voltage variances were observed between OK and NOK coils, with resonance frequencies appearing consistent. Further analysis revealed significant differences in peak-to-peak voltages across the coils when connected to a controller PCB. Elevated temperature data indicated resistance and inductance changes in the coils at room temperature and 80°C.
