The R73 Series is constructed of polypropylene film and metal foil or metallized film and metal foil with radial leads of inned 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. Two different winding constructions are used depending on voltage parameters. Please see the Performance Characteristics for more information. Automotive grade devices are available (up to lead spacing 22.5 mm) and meet the demanding Automotive Electronics Council's AEC–Q200 qualification requirements. Typical applications include deflection circuits in televisions (flyback tuning), switching spikes suppression in switched mode power supply (SMPS), snubber and silicon-controlled rectifier (SCR) commutation circuits, and switching circuits in electronic ballasts, as well as applications with high voltage and very high current. Not suitable for across-theline application (see Suppressor Capacitors).
