The SiT8918B provides a perfect combination of wide frequency range (1 MHz to 110 MHz), excellent stability (±20 ppm) and wide temperature range (-40 to 125 °C) in the smallest 2.0x1.6 mmxmm package that is not readily available from quartz. This device also features the industry's best shock and vibration resistance.

The SiT8918 comes in industry-standard packages and footprints, and therefore replaces quartz without any design changes.

For the same device in a SOT23-5 package, refer to the SiT2018B.
