Capacitors, specifically a CAP ALUM POLY model with a value of 680 microfarads (UF) and a voltage rating of 2.5 volts (V), are being used in this application. They are radial, can-style capacitors with an SMD mount and have a resistance of 13 milliohms (mOhm). The expected lifespan for these components is 2000 hours at an operating temperature of 105 degrees Celsius (°C).
