X7R Ceramic Image


X7R Ceramic


The Electronics Components, Assemblies & Materials Association (EIA) characterizes X7R dielectric as a Class II material.

Components of this classification are a fixed ceramic dielectric, generally made of Barium Titanate (BaTiO3). Typically they are used for bypass and decoupling applications.

X7R exhibits a predictable change in capacitance with respect to time and voltage. As the ambient temperature changes, there is a minimal change in capacitance.

Capacitance change is limited to ±15% from -55°C to +125°C.. For more information about EIA Classifications, see this FAQ on Temperature Coefficients.
