Coupling Capacitors

Coupling Capacitors Niroutrans
NTC coupling capacitors type CC01-CC12 are intended for power line carrier applicatons.
The insulator and capacitor design are identical to capacitor voltage dividers, but without an intermediate voltage terminal.
The dielectric used in the coupling capacitor consist of a combination of oil impregnated paper and polypropylene film, resulting in CC being practically impervious to temperature varication. A line trap can in most cases be mounted directly on top of the coupling capacitor.
