The Enable/Disable function draws 19 mA active and drops to 10 µA in shutdown — a microcontroller can gate the oscillator without external switching, cutting standby current on battery-powered or power-conscious designs. ## 3.2 × 2.5 mm SMT footprint and commercial grade Operating range is -20°C to 70°C, the commercial temperature band — suited for indoor electronics, office equipment, and industrial enclosures that do not expose the oscillator to the full industrial -40 °C cold end.","metaTitle":"ASE-44.000MHZ-ET Abracon 44MHz XO, 3.3V CMOS","metaDescription":"Abracon ASE-44.000MHZ-ET, 44 MHz CMOS crystal oscillator, ±100ppm stability, 3.3V supply, enable/disable, -20°C~70°C.
