Low-Profile Crystal Meets Bluetooth Height Requirements

Measuring only 0.8 mm in height and hermetically sealed in a SMD, ceramic base with a metal lid, the CM4 series crystal quartz resonator is available in the popular Bluetooth frequency of 32 kHz. The low-profile device is also available in frequencies ranging from 32 kHz to 1 MHz.
This crystal requires a drive level of 1 µW with ±3 ppm typical. Frequency tolerance is ± 30 ppm over an operating range of -40°C to 85°C.
Other key features include a current consumption of 1 µA, ± 3ppm aging maximum the first year, and high resistance to shock and vibration. Pricing for the CM4 at 32 kHz on tape-and-reel is set at $1.66 each/100,000. Delivery is from stock to 14 weeks ARO.
