40uF 7kV / 5kV High Voltage Pulse Power Capacitor. New! Lot of 2pcs
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). 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.
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. Nominal Working Voltage: 5000 VDC.
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.
