Microchip lists the DSC1030BI1-066.6666T as Obsolete. Housed in a 4-SMD no-lead package measuring 5.00 mm × 3.20 mm with a seated height of 0.90 mm, the oscillator occupies a standard 5×3.2 mm MEMS oscillator footprint. The surface-mount package reflows with standard lead-free profiles; no special via-in-pad or thermal pad is required.","metaTitle":"DSC1030BI1-066.6666T Microchip MEMS Oscillator – Obsolete","metaDescription":"DSC1030BI1-066.6666T Microchip MEMS XO, 66.6666 MHz, CMOS, 3V, -40°C to 85°C.
