The HC-45/U Cold Weld precision miniature crystal is ideally suited for the manufacture of precision - December 2015

The HC-45/U Cold Weld precision miniature crystal is ideally suited for the manufacture of precision AT and SC cut high reliability resonators where space is limited. This is the smallest available package in the quartz crystal cold weld series. The small volume allows for fast thermal transmission and the high vacuum environment ensures the best possible ageing and phase noise performance.

With frequencies ranging from (8 ~ 220) MHz, this crystal can custom designed or we can offer our best standard specification. They are used in primarily OCXO applications but in TCXO and VCXO as well. They have better parameters than can be achieved using the UM1 which is the resistance weld equivalent.
It has excellent long term aging and in many cases a significant increase in Q factor. They are necessary for making SC cuts as they are evacuated not filled with Nitrogen as in the UM1.In some cases they are a suitable substitute for HC 43/U when a reduction of size of oscillator is required.

Specific ordering information is available upon request for bespoke designs, if you require assistance our excellent design engineer is available to deal with your enquiries.
