thick film resistors high voltage glaze glass - ri82

thick film,resistors


ri82 chip type are able to absorb large amounts of energy at high voltage while remaining non-inductive. ideal for: capacitor crowbar circuits, impulse voltage generators, energy research, pulse modulators, radar pulse-forming networks, high voltage snubber circuits, arc furnace damping, x-ray/imaging equipment, and emi / lightning supression. this general line of high voltage resistor is available in a wide variety of sizes and terminations. they retain the non-inductive and heavy load characteristics. ri82 can handle up to 30 kv.
