The ECS-40.3-20-4 is a quartz crystal from ECS Inc. designed for frequency control applications. It operates at a fundamental frequency of 4.032 MHz with a load capacitance of 20 pF. The frequency tolerance is ±30 ppm at 25°C, and frequency stability is ±50 ppm over the operating temperature range of -10°C to +70°C. The equivalent series resistance (ESR) is 150 Ω maximum. This crystal is housed in a low-profile HC-49/US through-hole package with radial leads, measuring 11.35 mm x 4.65 mm x 3.50 mm. It is suitable for use in microcontrollers, clock generation, and timing circuits. The part is RoHS3 compliant and has an MSL rating of 1.
