The 0603YC104JAT2A is a Multilayer Ceramic Capacitor with Ni/Sn-plated termination, X7R dielectric and 0603 case. A multilayer ceramic (MLC) capacitor is a monolithic block of ceramic containing two sets of offset, interleaved planar electrodes that extend to two opposite surfaces of the ceramic dielectric. X7R formulations are called temperature stable ceramics and fall into EIA class II materials. X7R is the most popular of these intermediate dielectric constant materials. This capacitance change is non-linear. Capacitance for X7R varies under the influence of electrical operating conditions such as voltage and frequency. X7R dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.
