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.
