About US

Krystaly, Hradec Králové a.s.

The company KRYSTALY, Hradec Králové, a.s. is a business unit which is primarily focused on the production of custom-made components based on Synthetic Quartz, alternatively on other piezoelectric materials. The main fields of company’s activities are based on the properties of these materials due to which the components are used to stabilize and filter frequencies in electronics and electromechanical sensors in industry. There are three main fields of interest: production and sale of piezoelectric Quartz Crystal Units, production and sale of assembled components (i.e. Monolithic Quartz Crystal Filters, Quartz Crystal Filters, Oscillators). The third field is focused on the production of Quartz Substrates for filters with Surface Acoustic Wave (SAW) which are used in telecommunications, sensors and other SAW applications.

In the aforementioned fields we offer customized products on the basis of agreed parameters required by a customer. The company’s key strength is a short delivery time; prompt response to customer’s needs and small quantity orders. In the field of Quartz Crystal Units we focus, as one of the few companies in the world, on channel crystals used both in professional applications and amateur applications. The technology utilized in Quartz Substrates production also enables to process other materials used in electronics such as lithium-niobate and lithium-tantalate. We offer renewal of these substrates by re-polishing.

For all our branches we have regular customers from Europe, USA and countries all over the world. Our company staff consists of 80-90 qualified employees. Our own R&D provides development of the aforementioned fields in the frame of current trends and innovations and helps to specify customer requirements when needed.

In 2001 our company was certified to ISO 9001:2000. At the present we have certification of ISO 9001:2015 and ISO 14001:2015.


Production of piezoelectric resonators in Hradec Králové started in year 1952, when research and development results of universities and R&D center in Prague were transferred to Hradec Králové and production shop was established. In 1964 the name of company changed to TESLA n.p. Hradec Králové, later transformed into TESLA group of companies.
Production of Quartz Crystal Units was given support by purchase and introduction of TELEQUARZ technology, and productivity was improved and range of products changed according to customer requirements. After year 1989 company changed to stock company and then in 1993 Quartz Crystal Unit branch was separated and KRYSTALY, a.s. was founded, and started its own independent business. Starting in 1996 under the name KRYSTALY, Hradec Králové, a.s. new branch of business was integrated to existing ones, production of Quartz Crystal Wafers for SAW filters.
Through years 2000 – 2001 company improved, using own resources, production facilities and permanently developed all 3 main branches focusing all main investments into filter production. Influenced by customer requirements changes filter branch became load-bearing one, where production partly oriented into field of filters in ceramic packages.
Bearing in mind partial decrease of production through years 2008 and 2009, company is stable supplier of its own products into EU region, domestic and other countries all over the world.
