The ECS-122.8-18-4XEN is a 12.288 MHz quartz crystal from ECS Inc. designed for through-hole mounting in the HC-49/US package. It operates in fundamental mode with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 60 Ω maximum. The crystal offers a frequency tolerance of ±30 ppm at 25°C and a frequency stability of ±50 ppm over the operating temperature range of -40°C to +85°C. This makes it suitable for general-purpose timing applications in industrial and consumer electronics. The HC-49/US package measures 11.35 mm x 4.65 mm x 3.50 mm, providing a low-profile solution for PCB designs. The crystal is RoHS3 compliant and has an MSL rating of 1 (unlimited). It is commonly used in microcontrollers, communication interfaces, and clock generation circuits.
