The 04023C472KAT2A is a surface-mount (SMT) Multilayer Ceramic Capacitor with Ni and Sn plated terminations. The 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. Its temperature variation of capacitance is within ±15% from -55 to 125°C. This capacitance change is non-linear. Capacitance for X7R varies under the influence of electrical operating conditions such as voltage and frequency. The X7R dielectric chip usage covers the broad spectrum of industrial applications where known changes in capacitance due to applied voltages are acceptable.
Ceramic chips consist of formulated ceramic dielectric materials which have been fabricated into thin layers, interspersed with metal electrodes alternately exposed on opposite edges of the laminated structure. The entire structure is then fired at high temperature to produce a monolithic block which provides high capacitance values in a small physical volume. After firing, conductive terminations are applied to opposite ends of the chip to make contact with the exposed electrodes. Kemet ceramic chip capacitors are offered in the five most popular temperature characteristics: C0G (NP0) ,X7R, X5R,Z5U & Y5V.
