The ECS-80-20-5PXDU-TR is a CSM-7XDU series surface-mount crystal that provides a stable 8.000 MHz clock source. It is specified with a 20 pF load capacitance and features a frequency stability of ±100 ppm across a wide operating temperature range of -55°C to +125°C. This component has a tight frequency tolerance of ±30 ppm at 25°C and a maximum ESR of 60 Ω while operating in its fundamental mode. Housed in a low-profile, 4.3 mm height package, this RoHS compliant crystal is ideal for applications requiring a reliable timing reference in harsh thermal environments.
