ELECTRICAL SPECIFICATIONS

GENERAL DESCRIPTION

The SMM series SMPS capacitors incorporate the Super X7R dielectric

material. AVX SMM stacked capacitors offer high dielectric constant (K)

characteristics allowing for an extended capacitance range. The higher

capacitance values in the smaller case sizes reduce the amount of board

space needed to mount these components. The SMM series capacitors

are designed for use in applications ranging from high end DC/DC convert-

ers to general power supplies, telecom networks, snubbers, aerospace

instrumentation panels, hybrid power applications and more.
