Murata Electronics has developed the XRCGB-F1S series crystals. It provides improved temperature characteristics and lower frequency tolerance (+-10ppm). Using a silicon conductive paste in the construction process, they are able to achieve a reduction in temperature variation characteristics across the temperature range.
Additionally, the new -F1S series achieves better performance characteristics after reflow soldering. The new XRCB-F1S series is available in 38.4 MHz which is a common timing frequency for wireless communication such as BLE, Sub GHz, Zigbee and others.
