The Kemet C series commercial grade multilayer ceramic chip capacitors is Class 2, X7R dielectric material which exhibits no change in capacitance with respect to time and voltage. There will be negligible change in capacitance with reference to ambient temperature. Standard end terminations use a nickel barrier layer and a matte tin finish to provide excellent soldering ability for customers. Typical applications include decoupling, bypass, filtering and transient voltage suppression. MLCCs are monolithic devices that consist of laminated layers of specially formulated, ceramic dielectric materials interspersed with a metal electrode system. The layered formation is then fired at high temperature to produce a sintered and volumetrically efficient capacitance device. A conductive termination barrier system is integrated on the exposed ends of the chip to complete the connection.
The C1210X475K5RACTU is a surface-mount Multilayer Ceramic Chip Capacitor with 100% matte Sn flexible termination, 1210 case and X7R dielectric. A conductive silver epoxy is utilized between the base metal and nickel barrier layers of KEMETs standard termination system in order to establish pliability while maintaining terminal strength, solderability and electrical performance. This technology was developed in order to address the primary failure mode of MLCCs-flex cracks, which are typically the result of excessive tensile and shear stresses produced during board flexure and thermal cycling. Flexible termination technology inhibits the transfer of board stress to the rigid ceramic body, therefore mitigating flex cracks which can result in low IR or short-circuit failures.
The AVX multilayer ceramic capacitors with EIA class II, X7R dielectric material are temperature stable ceramic chip capacitors. This multilayer ceramic capacitor is a monolithic block of ceramic containing two sets of offset, interleaved planar electrodes that extend to two opposite surfaces of ceramic dielectric. Capacitance for X7R dielectric varies under influence of electrical operating conditions such as voltage and frequency. X7R dielectric chip usage covers broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.
