C1206 Series. Kemet C1206 series X5R and X7R dielectric surface mount capacitors features a high maximum operating temperature. The Electronics Components, Assemblies & Materials Association (EIA) characterizes the dielectric as a Class II material. Components of this classification are fixed, ceramic dielectric capacitors suited for bypass and decoupling applications or for frequency discriminating circuits where Q and stability of capacitance characteristics are not critical. Lead-Free, RoHS, and REACH Compliant Temperature stable dielectric Non-polar Matte tin-plated terminations
