Polypropylene Pulse/High Frequency Capacitors R74, Single Metallized Polypropylene Film, Radial, AC Applications (Automotive Grade) Overview Applications The R74 Series is constructed of metallized 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 94 V–0 requirements.
