Polypropylene Pulse/High Frequency Capacitors
A70, Single Metallized Polypropylene Film, Axial
Overview
The A70 Series is constructed of metallized polypropylene
film 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.
Applications
Typical applications include temperature compensation
circuits, timing, oscillator circuits, power factor correction,
and coupling capacitors in switched mode power supply
(SMPS) applications. Not suitable for across-the-line
application (see Suppressor Capacitors).
