The ECS-40-20-5PDN-TR is a 4 MHz fundamental mode quartz crystal from ECS Inc., part of the CSM-7 series. It is designed for surface mount applications and comes in a compact HC-49/US package with a maximum height of 4.30 mm. The crystal features a load capacitance of 20 pF, a frequency tolerance of ±30 ppm at +25°C, and a frequency stability of ±100 ppm over the extended temperature range of -40°C to +85°C (DN option).
Electrical characteristics include a maximum equivalent series resistance (ESR) of 150 Ω for the 3.570 to 4.999 MHz fundamental range, a shunt capacitance of 7.0 pF, and a drive level of 0.5 mW. The aging rate is ±5 ppm in the first year at +25°C. The crystal is supplied in tape and reel packaging with a standard quantity of 1000 pieces per reel.
This crystal is suitable for general-purpose timing and frequency control applications requiring a stable 4 MHz reference. The surface mount HC-49/US package allows for automated assembly and is compatible with standard reflow soldering processes. The extended temperature range makes it appropriate for industrial and automotive environments where temperature extremes are encountered.
The nominal frequency is 4 MHz.
The load capacitance is 20 pF.
The operating temperature range is -40°C to +85°C.
The package is HC-49/US, surface mount.
It is listed as RoHS3 compliant.
The frequency tolerance is ±30 ppm at +25°C.
The maximum equivalent series resistance is 150 Ω.
