SMPS Capacitors (SK Style)
Commercial Radial Range
PRODUCT OFFERING – C0G, X7R AND Z5U
AVX SK styles are conformally coated MLC capacitors for input or output
filtering in switch mode power supplies. They are specially processed to
handle high currents and are low enough in cost for commercial SMPS
application.
