100 & 200 Series Bulk Ceramic Axial Lead Resistors 100 & 200 Series Axial Leaded Non-Inductive Bulk Ceramic Resistors provide excellent performance where high peak power or high-energy pulses must be handled in a small size. The advantage of the bulk construction is that it 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. We offer a full line of rugged, reliable ceramic resistors including custom designs. Three distinctly dif- ferent ceramic materials are available in each size to FeatureS afford the designer with unique components to meet the most demanding requirements.
