UNITS
CRYSTAL UNITS FOR CAR ELECTRONICS (AT-51 SERIES)
These crystal units are ideally suited for clock signal generating sources for CPUs for power trains and safety control
devices requiring extremely high reliability as an electronic part used in a car.
s Features
8 High stability under strict conditions in terms of stable start-up characteristics, heat resistance, thermo-cycle resistance
and vibration resistance.
For further details, please contact us.
8 Surface mount crystal unit that retains high-level electrical characteristics and reliability due to the resin seating
attached to the AT-51 type crystal unit.
