. Inductive Series resonant freq Frequency Parallell resonant freq Capacitive Crystals below 30MHz can be operated at any frequency between the series and parallel resonant frequencies, which means that they are inductive in operation. High- frequency crystals above 30MHz are usually operated at the series resonant frequency or overtone frequencies, which occur at multiples of the fundamental frequency.
