Polypropylene Pulse/High Frequency Capacitors
R71, Single Metallized Polypropylene Film, Radial,
SMPS PFC Applications
Overview
The R71 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 UL 94 V–0
requirements.
Applications
Typical applications include power factor correction
and pulse applications. Not suitable for across-the-line
application (see Suppressor Capacitors).
