AVX/Kyocera Ceramic Resonators
GENERAL DESCRIPTION
ceramic resonators covering both the kilohertz and
megahertz frequency ranges. The high quality and extensive
coverage of this product line allows optimum design of
almost any oscillating circuit.
oscillators and LC/RC oscillators in regard to accuracy but
are considerably smaller, require no adjustments, have
improved start-up times, and are low in cost.

structure. These materials (usually barium titanate or lead-
zirconium titanate, PZT) have large dipole movement which
causes the distortion or growth of the crystal by an applied
