Outline and Dimensions

Custom crystal service

Due to the custom-designed nature of High Frequency Fundamental

(HFF) crystals, Euroquartz produce HFF crystals to customer s

specifications. There is a short lead time from design to production

for these parts. Contact Euroquartz application engineers to discuss

your requirements.
