The ECS-250-20-3X-EN-TR is a 25.0000 MHz quartz crystal from ECS Inc., part of the miniature CSM-3X series. This surface mount device is housed in a low-profile HC-49/US package measuring 7.00mm x 4.10mm x 2.30mm, making it suitable for space-constrained designs.
Electrically, the crystal offers a frequency tolerance of ±30 ppm and frequency stability of ±50 ppm over the full operating temperature range of -40°C to +85°C. It requires a 20 pF load capacitance and has a maximum equivalent series resistance (ESR) of 50 Ω. The crystal operates in fundamental mode with a maximum drive level of 100 μW.
The CSM-3X package features a resistance weld construction and is RoHS compliant with a matte tin/copper lead finish. It is rated MSL 1 (unlimited) and is supplied in tape and reel packaging with 3000 pieces per reel, suitable for automated assembly processes.
The nominal frequency is 25 MHz.
The required load capacitance is 20 pF.
The operating temperature range is -40°C to +85°C.
Yes, it is RoHS3 compliant and Pb free.
The package is HC-49/US surface mount, part of the CSM-3X series.
The maximum equivalent series resistance (ESR) is 50 Ω.
Frequency stability is ±50 ppm over the operating temperature range.
