Polymer Capacitors: SP-Cap Polymer Aluminum

SP-Cap Polymer Aluminum design engineers Panasonic
SP-Capacitor Special Polymer Aluminum
  • SP-Caps are Surface Mount Aluminum Electrolytic Capacitors that use a conductive polymer as their electrolyte material.
  • SP-Caps are primarily used as input and output capacitors for DC/DC converters due to their ultra low ESR values.
  • Panasonic SP-Caps offer excellent performance for moderate to high capacitance and voltage values at low cost.
