X5R dielectric series is “semi-stable” due to the maximum operating temperature of 85° X5R exhibits a predictable change in capacitance with respect to time and voltage and boasts a minimal change in capacitance with reference to ambient temperature. Capacitance change is limited to ±15% from -55°C to +85°C Applications include bypass and decoupling and for frequency discriminating circuits where Q and stability of capacitance characteristics are not critical
The C0G dielectric operates at a maximum of 125°C, and is stable Capacitance is not affected by a change in voltage and time These are temperature compensating and thus suitable for resonant circuit applications or those where Q and stability of capacitance characteristics are required Capacitance change is limited to ±30ppm/ºC from -55°C to +125°C
The KEMET X5R dielectric features an 85°C maximum operating temperature and is considered semi-stable. The Electronics Components, Assemblies & Materials Association (EIA) characterizes X5R dielectric as a Class II material.
