SMPS Stacked MLC Capacitors
(SMM Style) Extended Range
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.
