Not qualified for engine bay or outdoor telecom enclosures. The 0.50 mm pitch perimeter pads require a soldermask-defined pad on the PCB — a standard NSMD (non-solder-mask-defined) footprint risks tombstoning during reflow. Height is 0.90 mm max — low enough to fit under a 1.2 mm keep-out zone on the opposite side of a 1.6 mm PCB, but check the component-side clearance if the enclosure has a metal shield pressed against the board. The DSC400 series is Microchip’s current MEMS oscillator platform, so supply continuity is expected for the foreseeable future. No stock-holding claim — quoted to order.","metaTitle":"DSC400-0111Q0117KE1 MEMS XO – Triple Output 16.64/33/25 MHz","metaDescription":"Active production MEMS oscillator.
