impulse resistors - metal glaze series

impulse,metal glaze


ri80 is 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 tubular is available in a wide variety of sizes and terminations. they retain the non-inductive and heavy load characteristics. ri80 can handle up to 35 kv.
