A crystal unit, ideally suited for the clock signal generating source of the CPUs for power trains and safety control devices, requiring extremity high reliability as part of an automobile’s electronics system.
- Highly reliable under severe environmental conditions in terms of stable start-up characteristics, heat and heat-cycle resistance and vibration resistance.
- A surface-mount crystal unit that due to the resin seating attached to the AT-51 type crystal unit maintains high-level electrical characteristics and reliability.
- AT-51CD meets the requirements for re-flow profiling using lead-free solder.
