High Voltage MLC Radials (SV Style)
Application Information on High Voltage MLC Capacitors
High value, low leakage and small size are difficult parameters
to obtain in capacitors for high voltage systems. AVX special
high voltage MLC radial leaded capacitors meet these
performance characteristics. The added advantage of these
capacitors lies in special internal design minimizing the electric
field stresses within the MLC. These special design criteria
result in significant reduction of partial discharge activity within
the dielectric and having, therefore, a major impact on long-
term reliability of the product. The SV high voltage radial
capacitors are conformally coated with high insulation
resistance, high dielectric strength epoxy eliminating the
possibility of arc flashover.
The SV high voltage radial MLC designs exhibit low ESRs at
high frequency. The same criteria governing the high voltage
design carries the added benefits of extremely low ESR in
relatively low capacitance and small packages. These
capacitors are designed and are ideally suited for applications
such as snubbers in high frequency power converters,
resonators in SMPS, and high voltage coupling/DC blocking.
