High Voltage K75-40a Russian capacitor




 High-Voltage Big Power capacitor. NEW

40uF/5000V

The powerful High-Voltage K75-40 Russians capacitors they are made with use the modern material for internal insulator: POLYETHYLENE-TEREFTALAT. 

FEATURES:

? High impulse current rating up to 1400 A !

? Low self-inductance of < 40 nH

? High reliability and life expectancy

? Withstands heavy duty shock and vibration

? Non-polar dielectric - Dry, resin filled

Here is hoarfrost on capacitor. It have brought from-40C (-40F) strong Russian frost,hi.

But this capacitor can  work from -60C to +120C (-76F to 248F)

These power capacitors is really the best on the World!

See similar Sprague-Vishay capacitors: http://www.vishay.com/docs/13090/mkphcgen.pdf
Their $500 price  product has a 120A discharge current amplitude only, a small range of work temperatures and a fragile plastic-aluminium envelope. Also all electric parameters is more worse.

K75-40 is the best!

This quality is perfect also for use in the High Voltage Power Supply. It reduces pulsations is similar 120-150uF old oil capacitor! It is enough for use with anode current up to 2,0 amperes in one phase (witch 4,5kV to 9kW) or up to 10,0 amperes in 3 phase (with 4,5 kV to 45 kW) anode Power Supply. The best choice for pulsing loadings (CW and SSB big power high-linear amplifiers). These capacitors have no throws voltage and supplies of any front impulse of a anode current.

Material of electrodes:Composite of metals witch a special film coats

Material of insulator between electrodes: polyethylene-tereftalate

*********************************************

We have made HI-POT test for two 40uF/5kV capacitors:

We charged the capacitors up to 5000V with 50uA current, no problems and we got 8.6uA and 11,2uA leak current at 5000V. Next step was to charge it to 6000V, with 50uA current, no problems and we got 10.5uA and 13,1uA leak current at 6000V. 

   Absolutely safe for 6000VDc constantly without any limited!

  We increased the voltage to 7000V and got 29uA and 33uA leak current. Next step was to charge it to 7500V, with 60uA current,  at 7500VDc the self-discharge is still very small (46uA -> 0.05mA and 39uA->0.04mA) but we not recommend more 6500VDc for long term use.
