Polypropylene Pulse/High Frequency Capacitors
A72, Polypropylene Film/Foil, Axial
Overview
The A72 Series is constructed of polypropylene film and
metal foil or metallized film and metal foil with axial leads
of tinned wire. The axial leads are electrically welded to
the metal layer on the ends of the capacitor winding. The
capacitor is encapsulated in a polyester tape wrapping case
with thermosetting resin material. Two different winding
constructions are used depending on voltage parameters.
Please see the Performance Characteristics for more
information.
Applications
Typical applications include resonant circuit, high frequency
medium to heigh current, silicon-controlled rectifier
(SCR and IGBT) as well as applications with high voltage
and medium to high current.
Not suitable for across-the-line application
(see Suppressor Capacitors).
