3. CAPACITOR CLASSIFICATION
Multi-layer ceramic capacitors are available in wide range of characteristics. Electronic Industries Association (EIA) and the military have established categories to help divide the basic characteristics into more easily specified classes. The basic industry specification for ceramic capacitor is EIA specification RS-198 and as noted in the general section, it specifies temperature-compensating capacitors as class I capacitors. These are specified by the military under specification MIL-C-20. General-purpose capacitors with non-linear temperature coefficients are called Class II capacitors by EIA and specified by military under MIL-C-11015 and MIL-C-39014. The new high reliability military specification, MIL-C-123 covers both class I and class II dielectrics. Class I — Class I capacitors or temperature-compensating capacitors are usually made from mixtures of titanates where barium titanate is normally not a major part of mix. They have predictable temperature coefficients and in general, do not have an aging characteristic. Thus they are the most stable capacitor available. Normally the T.C.s of Class I temperature-compensating capacitors are NP0 (¡Ó 30 ppm/¢J ). Class II — General-purpose ceramic capacitors are called Class II capacitors and have become extremely popular because of the high capacitance values available in very small size. These capacitors are ferroelectrics and vary in capacitance value under the influence of the environmental and electrical operating conditions. Class II capacitors are affected by temperature¡B voltage¡B frequency and time. Temperature effects for Class II ceramic capacitors are exhibited as non-linear capacitance changes with temperature. Industry standards for Mid-K dielectrics, such as X7R and High-K dielectrics, such as Z5U and Y5V are defined as Class II formulations.

5. TECHNOLOGY
Multi-layer ceramic capacitor constructed by depositing alternative layers of ceramic dielectric materials and internal metallic electrodes, by advanced ceramic manufacturing technology, and co-firing into an indestructible homogeneous body, then completed with application of metal end terminations which are fired on to assure that permanent connection of individual internal electrodes are in parallel. The terminations also can be nickel-plated and then solder plated to give the chip capacitors nickel-barrier terminations which have much better leaching resistance during soldering. Reliable performances are built-in through exact formulation of dielectric powders, preparation of conductive paste, advanced automatic manufacturing, and strict quality control to assure excellent control in dielectric thickness, electrode integrity, and electrode-to-termination continuity.
