KP1-4 10 - 500pF 10kV Vacuum Variable Capacitor

Description

Due to the russian attack on Ukraine and the outbreak of war
normal logistics disrupted.
All parcels go through the west of Ukraine on the ground to Poland
As a result, the delivery time of parcels may be increased.

All new and used capacitors KP1-4 , KP1-12 ,  have dots on the plates
because electrical breakdown is part of a
technological process that should improve the vacuum. See paper
All capacitors have passed the process of gettering after long time storage and testing by me.
For this one:
C= max = 500 pF
U_testing = 10000 V
I_leackage =  > 0,5 uA
U_testing = 13000 V (30% above V max)
I_leackage =  > 1,0 uA ( without electric breakdown )
