This is a type of aluminum-polymer capacitor. It has a high capacitance value of 100 microfarads and operates at a voltage of 4 volts. The capacitors are radial in shape, have a can-style body, and are surface-mount device (SMD) compatible with an ESR of 22 milliohms. It is designed to last for up to 2000 hours when exposed to temperatures of 105 degrees Celsius.
