E1SBA18-25.000M TR

Crystals Overview

The E1SBA18-25.000M TR is a parallel resonant fundamental AT-cut quartz crystal resonator manufactured by Ecliptek. It operates at a nominal frequency of 25.000 MHz with a load capacitance of 18 pF. The component features a surface-mount HC-49/UP Short package, measuring 11.60 mm in length, 4.85 mm in width, and 3.20 mm in maximum height. Electrical specifications include a frequency tolerance of ±30 ppm at 25°C and ±50 ppm over the operating temperature range of -40°C to +85°C. Aging is limited to a maximum of 5 ppm per year, with an equivalent series resistance (ESR) of 40 ohms maximum and a drive level of 1 mWatt maximum.
