Polypropylene Pulse/High Frequency Capacitors
R74, Single Metallized Polypropylene Film, Radial,
AC Applications (Automotive Grade)
Overview
The R74 Series 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 the UL 94 V–0
requirements. Four different winding constructions are
used depending on voltage parameters. Please see the
Performance Characteristics for more information.
Automotive grade devices (up to lead spacing 22.5 mm) meet
the demanding Automotive Electronics Council's AEC–Q200
qualification requirements.
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).
