CRYSTAL UNITS
This is small leadless surface mount type crystal unit.
■Features
8Compact and thin (7.8×3.4×1.1 mm).
8Standard Nominal Frequency for PLL-system are lined up (ex. GSM, PDC, AMPS,
TACS, etc.).
8Frequency pullability performance absolutely required for temperature compensation.
8Frequency characteristics provide for easy temperature compensation owing to its sta-
ble characteristics close to crystal fit curve.
8It is applicable to IR Reflow.
8Taping package is for customer automatic loading operation.
8Display of temperature characteristics is possible using a two-dimensional data code.
