The R75 0.15μF 630V capacitor is constructed of metalized polypropylene film with radial leads of tinned wire. The radial leads are electrically welded to the metal layer on the ends of the capacitor winding. The capacitor is encapsulated in a self-extinguishing solvent-resistant plastic case with thermosetting resin material meeting the UL 94V–0 requirements. It is mainly used to repair the APW series power supply of Antminer.
