Product Description

Specially developed for extreme environments, the MCSO1EW is available at low frequencies from 10.0kHz to 20.0MHz. This rugged 3.3V oscillator offers extreme operating temperature range options, including -55 to +210°C, and features high shock and vibration resistance, perfect for extreme applications such as down-hole, avionics and geothermal designs.

The MCSO1EW has shock resistance of 10,000g (0.3ms, 1/2 sine) and vibration resistance of 40g (10.0~2,000Hz).

This miniature 7.86 x 3.6mm oscillator is available with SAC (Sn/Ag/Cu) tinned pad terminations, ideal for material-sensitive applications and manufacturing processes.
