Quartz Crystals and Oscillators – Accurate frequency for your application

Jauch frequency control products are produced and configured according to the highest quality standards. Therefore they provide reliable timing also under extreme conditions and for the most complex applications.

Quartz Crystals

Quartz crystals in SMD or pin versions, in the frequency 32.768 KHz and the MHz frequency range.

Quartz Crystal Oscillators

Quartz crystal oscillators for each application, also according to customer specifications.

MEMS Oscillators

MEMS oscillators configured with high shock and vibration resistance for your application.

Automotive Products

AEC-Q qualified quartz and MEMS oscillators




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.

Quality provides security

Our production know-how is also evident in quality assurance. This begins with the raw material selection: We use only high-quality, cutting angle measured blanks. We do regular audits of our suppliers as a matter of course and we get ourselves certified regularly.

Technical Support for your Frequency Components Solution

Starting with the development phase of your application, Jauch experts support you in selecting the optimal frequency component and in determining the required performance parameters and specifications. Implementing Jauch expertise in the beginning avoids costly mistakes and changes.

Upon request, we can analyze your crystal or oscillator circuit in our electronics laboratory. In the process, various parameters such as frequency accuracy, vibration tolerance and drive level can be examined. After completion of all tests, you will receive a detailed test report containing all important measured values as well as recommendations for action by our engineers to optimize the circuit.
