- Low
Inductance: Typically
a fraction of a microhenry. For example, a 50 kJ, 20 ohm resistor
has an inductance of 150 nH.
- Energy
Ratings: 10
to 1,000 kJ (1 MJ)
- Voltage
Ratings Up
to 500 kV
- Resistance
Values: 0.010
ohms to 100 kohms, ±10% (±1%
tolerances available upon request)
- Temperature
and voltage coefficients of resistance: few hundred
parts
per million per °C
- General
Atomics Energy Products High Energy resistors consist of a resistive
element
housed in a robust frame constructed of metal end terminals separated
by insulating angle bracket side rails. Standard resistors come in
several basic cross sections, with lengths from 6 to 48 inches. The
frame is designed to provide support for the resistor element and
dimensional stability to the entire assembly.
- The
metal resistor element is a folded ribbon strip connected to both
end plates. For
high current and low resistance (below 50 ohms) applications, the
element is a continuous, wide, flat strip of metal which is covered
with insulation
and folded, accordion style. For lower currents and high (above 50
ohms) resistance values, the element is a continuous, narrow metal
ribbon, spiral wound around a flat insulator ribbon, which is folded
accordion style.
- General
Atomics Energy Products resistor elements are generally a continuous
metal
winding with no welds or joints to cause electrical or mechanical
failures. The
open case, folded element design effectively dissipates heat and
allows for the use of forced air or oil cooling under severe conditions.
When
cooled by air or liquid flow, these resistors can be used for average
power dissipation which is beyond the capability of other conventional
resistors.
- The
materials used in the resistors have been carefully selected for
their mechanical,
electrical and thermal stability. The design of these resistors makes
them suitable for many applications where organic resistors fail
to perform.
- General
Atomics Energy Products High Energy resistors can be used in pulsed
or continuous
duty applications under high energy and high voltage conditions.
