RoHS Compliant SMPS Stacked
MLC Capacitors
(RMM Style) Extended Range
GENERAL DESCRIPTION
The RMM series SMPS capacitors incorporate the Super X7R dielectric
material. AVX RMM 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 RMM 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.
