High value, low leakage and small size are difficult parameters to obtain
in capacitors for high voltage systems. AVX special high voltage MLC
chips 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.
To make high voltage chips, larger physical sizes than are normally
encountered are necessary. These larger sizes require that special pre-
cautions be taken in applying these chips in surface mount assemblies.
In response to this, and to follow from the success of the FLEXITERM
®
range of low voltage parts, AVX is delighted to offer a FLEXITERM
®
high
voltage range of capacitors, FLEXITERM
®
.
The FLEXITERM
®
layer is designed to enhance the mechanical flexure
and temperature cycling performance of a standard ceramic capacitor,
giving customers a solution where board flexure or temperature cycle
damage are concerns.
