ECS-80-18-5PX-TR

The ECS-80-18-5PX-TR is a fundamental mode MHz crystal from ECS Inc. designed for surface mount applications. It operates at 8 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The crystal requires an 18 pF load capacitance and has a maximum equivalent series resistance (ESR) of 60 Ω. It is housed in a compact HC-49/US package measuring 11.40 mm x 4.80 mm with a height of 4.30 mm. The operating temperature range is -10°C to 70°C, making it suitable for general-purpose commercial electronics. The part is RoHS3 compliant and has an MSL rating of 1 (unlimited). The package code is 5PX, and the component is supplied in tape and reel packaging (indicated by the -TR suffix). This crystal is commonly used in timing circuits, microcontrollers, and communication devices requiring a stable 8 MHz reference.
