Impulse Resistors - Metal Glaze Series
Impulse Resistors - Metal Glaze Series
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.
