➢ Less heat generated during operations compared to standard Electrolytic Capacitors (Wet Caps)

➢ Highly conductive polymer cathode system

➢ Lower ESR & higher ripple capability

➢ Greater stability & longer life

➢ No electrolyte leakage leading to circuit board contamination

➢ No ignition

7 Advantages of Polymers
