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 TYPE AS TYPE BA 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. 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 BA 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.
