By using our LEDs and Modules
The clocking specialist CONTOC from Landsberg/Lech presents high-performance, low-cost MINI SMD crystals in a wide range of very small housings for bluetooth applications. These crystals are available in many different miniature ceramic casings like 1.6×1.2×0.3mm (SMD01612/4 series), 2.0 x 1.6 x 0.45 mm (SMD02016/4 series), 2.5×2.0x0.6mm (SMD02502/4 series) and 3.2 x 2.5 x 0.6 mm (SMD03025/4 series). All crystals can be supplied in an extended temperature range of up to -40/+125 °C with frequency tolerances at 25 °C from +-8 ppm and with temperature stabilities from +-8 ppm over 0/+70 °C. In addition to the classic bluetooth frequencies, the MINI SMD crystals cover a frequency range of 12 ~ 125 MHz depending on the size of the housing. If MINI SMD crystals with 32.768 kHz are used together with the Bluetooth MHz crystals, CONTOC’s product range includes cost-effective solutions in the following ceramic casings: 3.2 x 1.5 x 0.8 mm (M3215 series), 2.0 x 1.2 x 0.55 mm (M2015 series) and 1.6 x 1.0 x 0.45 mm (M1610 series). The standard frequency tolerance at 25 °C is +-20ppm. +-10 ppm versions can also be supplied on request. The standard temperature range for all 32.768 kHz crystals is -40/+85 °C. Versions with a range of up to -40/+125 °C are also available on request. The service portfolio of the specialists at CONTOC also includes circuit development, analyses, simulations and matching tests. “Everything from one source” is the philosophy at CONTOC, which aims to offer the customer an extremely short time to market.
