45 crystal units this is small leadless surface mount type crystal unit. features 8 compact and thin (7.8 3.4 1.1 mm). 8 standard nominal frequency for pll-system are lined up (ex. gsm, pdc, amps, tacs, etc.). 8 frequency pullability performance absolutely required for temperature compensation. 8 frequency characteristics provide for easy temperature compensation owing to its sta- ble characteristics close to crystal fit curve. 8 it is applicable to ir reflow. 8 taping package is for customer automatic loading operation. 8 display of temperature characteristics is possible using a two-dimensional data code.
