Tubular High Energy Bulk Ceramic
(continued)
The Ohmite Ceramic Resistor Division Tubular Non-
Inductive Bulk Ceramic Resistors provide excellent per-
formance for high peak power or high-energy pulses.
Bulk construction advantageously produces an inher-
ently 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 mate-
rials to allow designers to meet the most demanding
requirements.
Material composition type SP
is formulated to withstand high
operating temperatures result-
ing 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
Material composition type AS
is formulated to withstand high
energy and high voltage appli-
cations. 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.
Appplications
• Impulse generators
• High-voltage circuits
• X-ray equipment
• High voltage power supplies
• Laser/Imaging equipment
• Capacitor charge/discharge
Material composition type A is
formulated with to reach higher
resistance values. Maximum con-
tinuous 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.
Appplications
• Bleeder
• Capacitor charge/discharge
