The powerful High-Voltage K75-40 Russians capacitors they are made. With use the modern material for internal insulator. 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! Also all electric parameters is more worse. K75-40a series designed in the USSR for impulse discharge capacitors use in special radar stations more 3GWatt in pulse. Now it is applied as the energy storage in pulsing lasers. These capacitors are not inductive rather the big inductance of oil caps. These capacitors have small absorption of electrons and have in each impulse discharge of 100% of capacity rather 30-40% in any oil and 10-15% the pulse discharge in electrolityc capacitors. These pulse capacitors have small interior resistance and therefore very big current of the discharge in an impulse. This current in the hundreds times more a current of the discharge old oil capacitors!

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. POLARITY: Any DC or AC. Peak Working Voltage: 7500 VDC.

Discharge current amplitude: up to 1400 Ampers! Dissipation factor at f=50Hz: <0,008! Vibration 1-2000Hz witch acceleration: up to 10 G. Nonsingle shocks witch acceleration: up to 40 G.

Single shocks witch acceleration: up to 500 G! Temperature of work: -60 +120C (-76 to 248 F). Atmospheric pressure of work: 0,00012 to 294 000,0 Pa. Dimensions: 105x170x170 mm (4,1x6,7x6,7 in). Weight: 5.0 kg (11,0 lb).

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. Take the HUGE Power from the compact capacitor!
