Product Description

The ultra-miniature CM8V03-T1A offers a 32.768kHz solution with an ultra-low profile package of just 0.35mm, and high shock and vibration resistance within a miniature ceramic package with metal lid. The ultra-low profile of this crystal makes it suitable for a wide range of applications, including extremely close board stacking.

This tiny surface mount watch crystal is available in military and extended operating temperature ranges, and features low drive level of just 0.5uW max.

If you're designing for a high-volume commercial or consumer project and can accept a higher profile component, please consider our GWX-2012 or CM8V-T1A, 2012 form factor crystals as a more competitive option.
