The surface-mount package is compatible with automated pick-and-place and reflow assembly; the no-lead construction reduces parasitic inductance compared to a gull-wing package at 125 MHz. ## Active production status and sourcing posture","metaTitle":"DSC1101BI2-125.0031 MEMS XO 125.0031 MHz CMOS ±25 ppm -40°C","metaDescription":"Microchip DSC1101BI2-125.0031 MEMS oscillator, 125.0031 MHz CMOS output, ±25 ppm stability, 2.25V-3.6V supply, standby function.
