NX5032SD
Features
n
A small surface-mount type crystal unit, ideal for the special requirements of car
electronics, such as TPMS (Tire Pressure Monitoring System). The crystal unit is
ideally suited for the clock signal generating source of the transmission unit in a tire
wheel that is subject to strong centrifugal force.
Stable frequency characteristics even with a powerful centrifugal force of 2,000G,
