Fixed and variable vacuum capacitors for RF matching networks and high power tuning circuits, quoted against the CKT series designation you specify.
A matching network only works if the capacitor holds off the voltage at the frequency you run. Replacing one with the nearest thing in a distributor catalogue changes the tuning and the losses.

Both styles are listed. Tell us the series designation and the capacitance range you need and we will quote what is available.
The data we hold for the series together with price and availability, so the part can be checked against your circuit.
Yes. They are packed so that the terminals and the bellows are protected, and the packing is chosen for the freight method.
Send a photograph and the dimensions with the equipment type. That is usually enough to identify the series.
Send the numbers exactly as they are printed on your equipment. Price, availability and the data we hold come back by email.
