- Crystal Unit
A small surface-mount type crystal unit, ideal for Automotive.
Compatible with an engine control CPU clock delivering the high reliability that is particularly demanded, and compatible with low frequencies starting from 8 MHz.
Compact and thin. (5.0 × 3.2 × 1.1mm typ.)
Stable start-up characteristic even under extremely severe environmental conditions.
Excellent environmental characteristics, including heat, vibration and shock resistance.
Meets the requirements for re-flow profiling using lead-free solder.
Conforms to AEC-Q200.
