800 & 1000 Series
Tubular High Energy Bulk Ceramic
The Ohmite Ceramic Resistor Division Tubular NonInductive Bulk Ceramic Resistors provide excellent performance for high peak power or high-energy pulses.
Bulk construction advantageously produces an inherently non-inductive resistor; and it allows energy and
power to be uniformly distributed through the entire
ceramic resistor body – there is no film or wire to fail.
Ohmite offers a full line of rugged, reliable ceramic
resistors.
Ohmite offers three distinctly different ceramic materials to allow designers to meet the most demanding
requirements.
M at e r i a l T y p e s
Type
SP
Material composition type SP
is formulated to withstand high
operating temperatures resulting in high power dissipation.
Maximum continuous operating
temperature is specified at 350°C.
This type is suitable for use in oil
without an oil-resistant coating.
Appplications
• Motor drive circuits
• Snubber circuits
• High-frequency circuits
• RF dummy loads
• Dynamic braking
• Transformer protection
• Harmonic filter
Type
AS
Type
BA
Material composition type AS
is formulated to withstand high
energy and high voltage applications. Maximum continuous
operating temperature is specified
at 230°C. The standard dielectric
coating is recommended for use
in air, and the oil-resistant coating
is recommended for use in oil.
Material composition type A is
formulated with to reach higher
resistance values. Maximum continuous operating temperature is
specified at 230 C. The standard
dielectric coating is recommended
for use in air, and the oil-resistant
coating is recommended for use
in oil.

800 & 1000 Series
Tubular High Energy Bulk Ceramic
S p e c i f i c at i o n s
Series 800 and 1000 Tubular
Resistors are available in a
wide variety of sizes and terminations from 2" to 24" in
length and ½" to 2" in diameter.
These resistors can handle up
to 1000 watts, 165 kJ and 165
kV in resistance values from 1
ohm to 1 megohm.
* Allowable peak energy/voltage will depend on
the resistance value. Consult factory.
** Derate by 50% with oil resistant coating on
Type AS resistors. Energy ratings are based
on pulses
