Air Dielectric Trimmer Capacitors
Series MAV
The MAV range of air dielectric trimmers are specifi-
cally designed for high frequency applications that
demand extreme stability and a high 'Q' under severe
environmental conditions in a small physical size.
The internal shells are silver plated to provide optimum
surface conductivity and long life. A guiding element
maintains the rotor concentricity under extremes of
shock and vibration, and a rubber gasketted threaded
end cap provides seal against moisture and contami-
nants. All terminals are gold plated for optimum high
frequency conductivity and dependable solderability.
Solder coating on terminals is offered as an option.
The "Top-Tuned" styles were developed to enable the
more efficient use of mounting space in miniature
U.H.F
.circuits and are tuned at right angles to the mount-
ing surface. In addition to the standard model special
units can be manufactured which are designated with the
prefix SAV. For further information contact our Technical
Department.
