Accuracy
(at 25°C)
|
CO-437E: ±1 ppm
|
CO-457E: ±1 ppm
|
E= set to ±1 ppm via external capacitor (< MHz in CO-432 and <240MHz in CO-434/37 package)
|
Temperature Stability
Improved accuracy/stability available on some models. For example, for ±7 ppm over 0°C to +50°C and for ±10ppm over 0°C to +70°C. Improvement is also available over wider temperature ranges. Please contact factory.
