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).
