Crystal Unit is not always the same. Though the specifications of different manufacturers seem to be identical, every developer has certainly noticed that they behave in the circuit differently. This is why it is essential to receive the competent advice from an expert. The coftech GMBH is the specialised distributor for time & frequency products of the company Murata. In the last 40 years we have specialised in providing solutions with regard to quartz. The Murata quartz series HCR is suitable for consumer applications.
The focus lies on small dimensions (2.0 x 1.6 and 1.6 x 1.2 mm) for the use in the low-cost area. The product line of formerly Tokyo Denpa (TEW) mainly concentrates on telecommunications and medical technology. Professional applications require preconditions, such as narrow frequency tolerances ≤ ± 7 ppm, an excellent frequency stability and a good aging of ± 3ppm / 10 years.
HFF (High Fundamental Frequency) crystals up to 200 MHz are available in a housing of 5.0 x 3.2 mm. Not only the demand for higher frequencies continues, but also the miniaturization of crystals is progressing rapidly. coftech supplies the world's smallest quartz in a housing of 1.2 x 1.0 x 0.33 mm, the ideal clock generator for medical technology, smart cards and mobile phones.
