SBE Part 775D176980-102
Power Ring Film Capacitor™
17µF, 8,000Vdc
The 775D176980-102 Power Ring is
a 8,000Vdc, 17µF high voltage pulse
capacitor.
Electrical Specifications
SBE Part #:
775D176980-102
Capacitance/Tolerance: 17µF ±10%
DC Voltage Rating: 8,000Vdc
NOTE: This capacitor is specifically designed to
withstand repetitive pulse discharges at high
pulse currents with longer life than exhibited
by more typical metallized High Voltage film
capacitors. However, this capacitor is not recom-
mended for applications requiring continuous
voltage (constant charge) unless de-rated to
4,000Vdc Maximum. For a technical explanation
and further information on the intended uses for
this design please contact SBE engineering.
Dielectric/Construction: Patented pulse technology

Metallized Polypropylene film.

Series-section design,

non-inductively wound.
Dielectric Withstand Units 100% tested at DC
Voltage:
potential of 9,000Vdc for

two minutes at 25°C.
Peak-to-Peak Voltage: 10,000 V Max
When operated at this peak-to-peak voltage the
capacitor can be expected to withstand ~5,000
discharges.
Further reducing this value to 7,500 V peak-to-
peak will increase discharge life on the order of
10 times.
Further reducing this value to 5,600 V peak-to-
peak will increase this discharge life more than
1,000 times.
Reducing the Q of the discharge circuit will
improve shot life for all cases. End of life for the
above estimates is 10% capacitance reduction.
Insulation resistance: 5,000 MΩ Min at +25°C
ESR @ 10 kHz:

< 0.5 mΩ Min at +25°C,
typical
ESL:




~ 50 nH, minimum inductance
connection. The actual
capacitor loop inductance
will depend on the application
interconnect design.
Operating Temperature: -40°C to +85°C
Peak Current Rating: 34,500 Amps repetitive
