Polypropylene Pulse/High Frequency Capacitors
R79 Series Single Metallized Polypropylene Film, Radial,
5 mm Lead Spacing, Multipurpose Applications
Overview
The R79 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 94V–0 requirements.
Applications
Typical applications include timing, oscillator circuits, high
frequency coupling and decoupling applications. Not suitable for
across-the-line application (see Suppressor Capacitors).
