What is the spacing on the plates? Because I'am looking for this var- Cap in an ham radio linear amp for my ham station.I need to know the spacing of the plates because of Hi voltage RF.
Asked by Anonymous on January 27th, 2016.
The spacing is around 0.015" (~0.38mm). They are perfectly OK for tube receivers, but I would rate them at around 250V. For a linear HF amp, the capacitor is useful as a pi output capacitor, but you would need a higher voltage rating for a plate cap. For antenna tuners (tee or L), I would be reluctant to rate them in excess of 25-30W, because of the higher voltages encountered when matching reactive loads.
Does it have mounting holes on the bottom side?
Asked by Anonymous on June 28th, 2016.
Yes, there appears to be three threaded mounting holes on the bottom of this capacitor.
Is this 365 pf for each section or total?
Asked by Anonymous on August 10th, 2017.
Each section is going to be 365pf.
What the insulation is made of?
Asked by Anonymous on November 24th, 2017.
Insulation is made of air.
Would something as large as this tri-capacitor be appropriate for something like a am loop antenna?
Asked by Anonymous on April 25th, 2018.
Yes. single section, two or
three together, or use all three separate in a pi configuration or pi/tuning config.
Does this capacitor have stops?
Asked by Anonymous on June 14th, 2018.
The shaft on this capacitor travels approximately 180 degrees in one full sweep.
What is the height of this capacitor when the plates are opened to their highest (halfway) position? I have a chassis height limitation.
Asked by Anonymous on March 16th, 2019.
It is 2.08" at its highest point.
