ECS Electronic Component Highlight Surface Mount Crystals

The ECS-327MV will offer better overall performance than MEMS oscillators.

ECS’ ECS-327MV 32.768 kHz low current surface mount MultiVoltTM oscillator is available in a miniature 1.6 mm x 1.2 mm x 0.7 mm ceramic package. This component offers a frequency of 32.768 kHz and stability of ±25ppm at the standard industrial operating temperature of -40ºC ~ 85ºC. MultiVoltTM oscillators are compatible with 1.8 V, 2.5 V, 3.0 V or 3.0 V power supply. 

September 2022 Update 

ECS has released two additional part numbers in the ECS-327MV MultiVoltTM oscillator family with extended operating temperature options. The two new part numbers are ECS-327MV-DM-TR that offers a stability of ±20ppm at an extended -20ºC ~ 70ºC operating temperature and the ECS-327-CM-TR that offers a stability of ±25ppm at the -20ºC ~ 70ºC operating temperature range.
