6KV 14 - 90 pF MRI Air Space Capacitor made by Jackson Brothers EMS2
14-90pf 4kv Air variable capacitor for MRI application using Bearings for motor control.
made by Jackson Brothers
This was made for use in MRI units and other high voltage applications but is soldered with internal bearings so its very light and can be controlled by a small motor.
Its used also in loop antenna's
some applications may require higher current or voltage we can make other units or capacities
