EUROQUARTZ LPO42-C4

LOW POWER CONSUMPTION OSCILLATORS
LPO 42 SERIES, Model 4
OUTLINES AND DIMENSIONS
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.
