SP-Cap Aluminum Cap | PanasonicSP-CAP, or Specialty Polymer Aluminum Electrolytic Capacitor, was developed by Panasonic. It uses a specialty polymer (polypyrrole) electrolyte. The SP-Cap is based on aluminum electrolytic capacitor technology, but uses a solid polymer electrolyte.

The SP-Cap has very stable capacitance characteristics in both operating temperature and frequency compared to ceramic, polymer, and low ESR tantalum capacitors. In terms of safety, the SP-Caps do not easily ignite or “smoke,” even with a 1-A current applied or in the case of a short circuit. If a defect occurs, the polymer will become self-insulating and shuts off the flow of current. Panasonic's SP-Cap is an excellent choice when used in applications requiring noise absorption, ripple voltage reduction, and transient response.
