Dielectric Withstanding Voltage 25°C (Flash Test) 250% rated voltage for 5 seconds with 50 mA maximum charging current (500 Volt units @ 750 VDC) Life Test (1000 hrs) 200% rated voltage for at 125°C (500 Volts units @ 600 VDC) 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. *Hi-Rel screening for consists of 100% Group A (B Level), Subgroup 1 per MIL-PRF-49470.
