Nos competences en images - nos services - vos avantages


En tant que fabricant, nous savons ce qu’il vous faut

As well as economic benefits, our production facilities at various locations also provide our clients with the certainty that they can rely on the availability of their frequency control products.

Production and Development

Our frequency control products are manufactured in close cooperation with our production partners in Asia. Thanks to state-of-the-art, fully integrated in-line production systems, we achieve production volumes of well over 100 million components per month. When it comes to development of new products, we also work closely with our network of partners and thus take advantage of synergy effects.

At our German headquarters, we manufacture several hundred thousand quartz crystals per year in customer-specific designs.

Quality Assurance

At our German headquarters, we assure the quality of our frequency control products. Therefore we make use of state-of-the-art test procedures and the corresponding equipment.

Fully automatic MEMS configuration

The configuration of our MEMS oscillators is also carried out at our headquarters in Germany - fully automatic and cutomised to your requirements.
