CX4V-TF Datasheet, PDF (1/2 Pages) IQD Frequency Products Ltd – Quartz Crystal Specification

ISSUE 7; April 2016
Description
IQD’s ultra-miniature CX4V TF Statek quartz crystals are
hermetically sealed in surface mount ceramic packages and
custom laser-tuned to frequencies ranging from 30 kHz to 250
kHz. This high quality tuning fork resonator is intended for use
in Pierce (single inverter) oscillators with a maximum process
temperature not to exceed 260°C.
