Product Summary

High value, low leakage and small size are difficult parameters to obtain in capacitors for high voltage systems. AVX special high voltage MLC chip capacitor 1812AA102KAT1A meets these performance characteristics and is designed for applications such as snubbers in high frequency power converters, resonators in SMPS, and high voltage coupling/dc blocking. The 1812AA102KAT1A designs exhibit low ESRs at high frequencies. Larger physical sizes than normally encountered chips are used to make high voltage MLC chip products. Special precautions must be taken in applying the 1812AA102KAT1A in surface mount assemblies. The temperature gradient during heating or cooling cycles should not exceed 4℃ per second. The preheat temperature must be within 50℃ of the peak temperature reached by the ceramic bodies through the soldering process. Chip sizes 1210 and larger should be reflow soldered only. 1812AA102KAT1A may require protective surface coating to prevent external arcing. For 1825, 2225 and 3640 sizes, AVX offers leaded version in either thru-hole or SMT configurations (for details see section on high voltage leaded MLC chips).
