Please consult ECS for available Temp Range options of tight stability crystals.
Note 1: Crystals over 24.000 MHz will be 3rd overtone (if available on data sheet) unless fundamental
mode is requested. An "F" suffix after the package type indicates a fundamental mode i.e. ECS-300-S-1-F
would be a 30.000 MHz Fundamental mode crystal.
