Polypropylene Pulse/High Frequency Capacitors
NOT FOR NEW DESIGN
Applications
Typical applications include electronic lighting such as
automotive headlamps and ballasts, as well as pulse
applications with high AC voltage and high current in
combination with a high ambient temperature.
Not suitable for across-the-line application
(see Suppressor Capacitors).

R74, 125°C Single Metallized Polypropylene Film,
Radial, AC Applications (Automotive Grade)
Overview
The R74 125°C 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. Two different winding constructions are used
depending on voltage parameters. Please see Performance
Characteristics for more information.
Automotive grade devices meet the demanding Automotive
Electronics Council's AEC–Q200 qualification requirements.
