Maximum current draw is 3 mA typical, which keeps the thermal contribution negligible in a dense layout and suits battery-powered or thermally constrained designs where every milliamp is budgeted. ## Frequency stability and temperature grade The industrial temperature grade means it can sit in an unventilated control cabinet or an outdoor telecom enclosure that sees summer heat and winter cold — the MEMS die itself is rated beyond this window, but the package and test guardband are certified to the stated limits. ## Sourcing reality: obsolete, no official successor Each lot is traceable and verified; quantities are confirmed at quote time against the specific requirement.","metaTitle":"Microchip DSC6121CI2A-00AK MEMS XO, 25MHz/27MHz, CMOS","metaDescription":"Microchip DSC6121CI2A-00AK MEMS-based XO, dual output 25MHz & 27MHz, CMOS, ±25ppm, 1.71-3.63V, -40 to 85°C.
