The Arco trimmer (padder) capacitor type 30 has a ceramic base with walls that enclose and protect
the plates and mica films from damage. The spring of the brass plates helps prevent mechanical fatigue and
provides constant pressure when position of the adjusting screw is moved.
Capacitance: 115pF - 550pF
Working Voltage: 175V
Test Voltage: 350V
Insulation Resistance @ 25°C: 100,000MΩ min.
