High-Voltage BigPower capacitor.

NEW!

60uF 4000V/6000V

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 2000 A !

• Low self-inductance of < 30 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)

See similar Sprague-Vishay capacitors: $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!

K75-40a series designed in the USSR for impulse discharge capacitors. 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. 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 180-200uF old oil capacitor! It is enough for use with anode current up to 3,0 amperes in one phase (witch 4,5kV to 9kW) or up to 15,0 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.

We was made HI-POT test fortwo 60uF/4kVcapacitors:

Wecharged the capacitors up to 4000V with 50uA current, no problems andwe got 9.6uA and 10,2uAleak current at 4000V.Next step was to chargeit to 4500V, with 50uA current, no problems and we got 12.5uA and13,5uAleak current at 4500V. Next step was to chargeit to 5000V, with 50uA current, no problems and we got 20.5uA and 21,5uAleak current at 5000V.

Absolutely safe for 5000VDc constantlywithout any limited!
