EUROQUARTZ LIMITED Blacknell Lane CREWKERNE Somerset UK TA18 7HE EURO QUARTZ
DESCRIPTION
CX9SM crystals are designed for applications requiring very small footprint and low profile (<1.0mm). Using micro-machining processes this hermitaclly-sealed crystalensures high stability and low ageing.
FEATURES
Designed for infrared, vapour phase or epoxy mounting Low profile, (<1.0mm) hermetically sealed ceramic package Excellent ageing characteristics High shock and vibration resistance Full military testing available Available with glass or ceramic lid Custom designs available CX9SM CRYSTAL Ultra-Miniature SMD Crystal 14MHz to 250MHz HOW TO ORDER CX9SM AT CRYSTALS CX9 - S - C - SM1 - 49.0M, 100 / 100 / - / I 'S' if special, custom design.
