The ECS-40-20-4X is a 4.0000 MHz fundamental mode quartz crystal manufactured by ECS Inc. International. It is designed for general purpose frequency control applications requiring a stable and accurate clock source.
Key electrical specifications include a frequency tolerance of ±30 ppm at 25°C and frequency stability of ±50 ppm over the operating temperature range of -10°C to +70°C. The crystal requires a 20 pF load capacitance and has a maximum equivalent series resistance (ESR) of 150 Ω. The drive level is 500 μW typical, and shunt capacitance is 7 pF typical. First year aging is limited to ±5 ppm.
The crystal is housed in a low profile HC-49USX (3.5 mm height) resistance weld through hole package with matte tin/copper lead finish. It is RoHS3 compliant, REACH unaffected, and MSL 1 (unlimited). The part is lead free and suitable for wave soldering with a peak solder temperature of 260°C for 10 seconds.
The frequency is 4 MHz.
