Vacuum Variable
Capacitors for AM Transmitters
As the original designer and manufacturer of the vacuum variable capacitor,
Jennings has amassed over five decades of proven reliability and quality.
Features:
-
High Voltage Rating - High dielectric strength of a vacuum
plus freedom from dust contamination, humitidy etc, permits maximum
voltage rating for a given size and capacity.
-
High Current Rating - Low losses and copper construction permit
the handling of high RF currents with convection and water cooling.
-
Space Saving - For a given capacitance and voltage rating,
vacuum capacitors occupy a minimum amount of space
-
Low Losses - Losses in vacuum capacitors is so small that
for most applications they can be considered as neglible.Construction
materials and vacuum dielectric permit the handling of large RF currents
at high RF frequencies that would destroy capacitors with other dielectric
material.
-
Self Healing - Vacuum capacitors can withstand momentary overloads
that would permanently damage other dielectric materials
