The CAP ALUM POLY 330UF 20 2.5V T/H is a type of radial capacitor with a can design. It features aluminum-polymer construction and a capacitance value of 330 microfarads (µF) at a voltage rating of 2.5 volts. The specified tolerance for this capacitor is ±20%, indicating that the actual capacitance may vary by up to 20% from its nominal value. This capacitor has a relatively low resistance of 7 milliohms and an expected lifespan of 5000 hours when operated at 105 degrees Celsius.
