A ceramic capacitor is a fixed-value capacitor where the ceramic material acts as the dielectric. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes. The composition of the ceramic material defines the electrical behavior and therefore applications.
rupulous inspection of all processes as well as the finished product. KEMET not only manufactures its own high reliability ceramic capacitor (GR900), KEMET also manufactures MIL-PRF-123 product
Class I ceramic capacitors are characterized by high stability, low losses, and minimal variation in capacitance over various environmental conditions. The most common example of Class I ceramic capacitors are C0G (NP0) and U2J capacitors. Here are the key characteristics of Class I ceramic capacitors, particularly C0G:
Reliability in Ceramic Capacitors What do we mean? Ability for the capacitor, under normal conditions, to operate within the specification over it’s lifetime with few or no failures. What we don’t mean Excessive Mechanical Stress (Flex) Excessive Voltage Excessive Temperature Voltage Transients The Bathtub Curve
A high degree of precision and control of process parameters is necessary to keep the scattering of electrical properties for today's very thin ceramic layers within specified limits. The voltage proof of ceramic capacitors is specified as rated voltage (UR).
In addition, power electronics applications are an emerging market in which ceramic capacitors will play an increasing role through improved breakdown strength, enhanced dielectric stability in harsh environments, and innovative packaging.
