Capacitor Assemblies SV2220 The SV capacitor assemblies are a vertical stacking of ceramic capacitors, offering far superior performance than either aluminum or tantalum electrolytic capacitors. They can be made with up to 10 same size chips with various lead configurations to safeguard against thermal and mechanical stresses and are 100% tested for dielectric withstanding voltage, insulation resistance, capacitance, and dissipation factor. They are ideally suited for the input and output stages of switch-mode power supplies and DC-DC converters, the SV capacitor assemblies offer several key benefits: Reduces the overall circuit board footprint High capacitance to volume ratio Low ESR and low ESL Capability to handle high ripple currents at high frequencies ELECTRICAL SPECIFICATIONS DIELECTRIC WITHSTANDING VOLTAGE: 250% of rated voltage for 5 seconds INSULATION RESISTANCE AT 25C: 500 mega-ohm/micro-farad minimum INSULATION RESISTANCE AT 125C: 50 mega-ohm/micro-farad minimum CAPACITANCE AT 25C: 1.00.2 VRMS at 120 Hz DISSIPATION FACTOR AT 25C 5% maximum at 1.00.2 VRMS at 120 Hz LIFE TEST: 150% of rated voltage at 125C for 1000 hours MOISTURE RESISTANCE: 10 cycles without voltage.
