Polypropylene Pulse/High Frequency Capacitors
R77 Series 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 94V–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).
