        Our company has a scientific research and production history of than 30 years in producing crystal. The three main categories of products are quartz crystal resonators, crystal oscillators (including surface mounted components) and crystal filters. We have more than 1,000 specifications and models. Annual production capacity reaches over 60Mpcs. Our company's main products include: quartz crystal resonators - resistance welding crystal resonators, cold pressure welding crystal resonators and SMD crystal resonators; crystal oscillators - SMD crystal oscillators, clock crystal oscillators, voltage controlled crystal oscillators, temperature compensated crystal oscillators, temperature compensated voltage controlled crystal oscillators and constant temperature crystal oscillators. Crystal filters - monolithic crystal filters, cascaded monolithic crystal filters and discrete crystal filters.

        The company has three military standard production lines, namely quartz crystal components production line, SMD surface mounted oscillator production line and high reliable quartz crystal components production line.

        Our company has strong capabilities of product development and batch production, and its comprehensive ability ranks among the forefront of the same industry.Our company has successively imported the world's advanced production, testing, screening, testing equipment and instruments from the United States, Japan, Germany and other countries; is one of the five designated enterprises which have the most complete product varieties in the piezoelectric quartz crystal industry and can provide key national weapons and equipment.
