The R75QI21005000J 10000 pF Film Capacitor 250V 1000V (1kV) Polypropylene (PP), Metallized Radial is a high-performance, general-purpose capacitor manufactured by Kemet. It is constructed using an ECO-friendly, metallized polypropylene film with an axial leaded radial package. This capacitor has a rated voltage of up to 1000V (1kV), meaning it can easily handle most heavy-duty applications. Additionally, it has a fairly high capacitance rating of 10000 pF (meaning it can easily store and discharge a lot of energy in a relatively small area), and its capacitance tolerance is +/- 20%. The R75QI21005000J also features excellent feedback features and low ESR, making it an excellent choice for high-reliability and power applications, such as high-end audio amplifiers and power supplies.
