SERIES 500SP NON-INDUCTIVE BULK CERAMIC SLAB RESISTORS

KANTHAL GLOBAR Series 500SP Non-Inductive Bulk Ceramic Slab Resistors provide high power and energy dissipation in a compact size. Proprietary bulk ceramic “SP” material is used in a simple, efficient design that permits energy to be uniformly absorbed throughout the resistor body, thereby avoiding failure in a peripheral film or wire. The advantages of KANTHAL GLOBAR Bulk Ceramic Slab Resistors include: • Typical Applications: • • • • • • • • Inherently non-inductive, high reliability due to bulk ceramic Series 500SP Non-Inductive Bulk Ceramic Slab Resistors construction 15 watts per inch of...
