TPSM32A - 2B Elettronica

TPSM32A Quartz Crystal

Crystals are realized with NT cut, in order to achieve low resonance frequency values (30KHz/80KHz). Widely used to generate internal time reference in PC, Mobile phones, microprocessors applications. 40KHz is standard frequency for ultra-sounds generators. 77.5KHz is, instead used to phase in lock with European broadcast time signal. Such crystals are also .
