CRYSTAL RESONATORS Resistance Weld Type #ii3#@kinst UM-4, UM-5, UM-1, UM-2, HC-49/T, HC-50/T, HC-49/U, HC-50/U UM series crystal resonators, which have outstanding frequency stability, are most suitable for pagers and mobile radiotelephone equipment. These high-reliability crystal resonators offer miniaturization without downgrading electrical characteristics of the crystal resonators. These crystals aiso have excellent impact shock and vibration resistance. HC series crystal resonators are used as a clock reference for microprocessors. They also offer frequency stability.
