High value, low leakage and small size are difficult parameters to obtain in capacitors for high voltage systems.
AVX special high voltage MLC chip capacitors meet these performance characteristics and are designed for
applications such as snubbers in high frequency power converters, resonators in SMPS, and high voltage
coupling/dc blocking. These high voltage chip 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 these chips in surface mount assemblies. The temperature gradient during
heating or cooling cycles should not exceed 4ºC per second. The preheat temperature must be within 50ºC of
the peak temperature reached by the ceramic bodies through the soldering process. Chip sizes 1210 and larger
should be reflow soldered only. Capacitors 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)
