LOW POWER CONSUMPTION OSCILLATORS LPO 42 SERIES, Model 4 4 pad SMD Package
DESCRIPTION
The Euroquartz LPO42 series of low power consumption oscillators are ideal parts providing the time base signals for real-time clocks. The oscillators have very low current consumption (as low as 14mA) and are ideal for battery operated devices such as data logging and portable test equipment.
