Polypropylene Pulse/High Frequency Capacitors
R77, Double Metallized Polypropylene Film,
Radial, AC Applications
Overview
The R77 Series is constructed of polypropylene film and
double metallized polyester film as electrodes 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. Four different winding
constructions are used depending on voltage parameters.
Please see the Performance Characteristics for more
information.
Applications
Typical applications include electronic lighting such as
automotive headlamps and ballasts, as well as pulse
applications with high AC voltage and high current.
Not suitable for across-the-line application
(see Suppressor Capacitors).
