Unlike quartz crystal oscillators, the MEMS resonator is immune to vibration-induced frequency shifts and has no crystal aging drift—a practical advantage for industrial environments where mechanical shock is present. ## Standby mode cuts supply to 1 µA for battery-powered holds ## Industrial temperature grade and 3.2 mm × 2.5 mm footprint The 4-SMD no-lead package measures 3.20 mm × 2.50 mm with a seated height of 0.90 mm—compatible with standard reflow profiles and tight board stacks.","metaTitle":"DSC1033CI2-037.1250T MEMS XO 37.125 MHz CMOS ±25ppm","metaDescription":"Microchip DSC1033CI2-037.1250T MEMS oscillator, 37.125 MHz, CMOS output, ±25ppm stability, 3.3V, industrial temp, active production.

The MEMS resonator eliminates quartz aging and vibration sensitivity, but the pinout and supply voltage match the standard footprint—confirm your PCB's enable/power-down pin assignment against the datasheet."},{"question":"Does the DSC1033CI2-037.1250T have a standby mode?","answer":"Yes, the function is Standby (Power Down).
