Impulse Resistors - RI80 series are able to absorb large amounts of energy at high voltage while remaining non-inductive. Token Impulse Resistors are primarily designed for impluse surging lines and conform to the RoHS directive and Lead-free. Impluse resistors can be customed designs and tighter tolerances available on request. Application of impluse specific designs also available including different voltage and power specifications adjusted to resistance requirements. 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.
