Micro Crystal is offering a lower ESR (effective series resistance) version of its tuning-fork 32.768 kHz crystal, claiming that the low impedance crystals “extend the oscillator safety margin, where standard crystals are on the limit”. With hermetic sealing (gold-tin preform, ceramic package, metal lid), it operates under vacuum. Application is expected in : wearables, activity bands, ...
