Pulse-withstanding resistors are used to dissipate excess energy from high power circuits. During transient or overload conditions, these high energy resistors safeguard the equipment from energy surges (upto thousands of Joules) for short durations. Read More
Carbon composition resistors, wire wounds or thick film resistors are commonly used due to their surge handling capabilities. Materials with low inductance are more suitable.
The application must also be able to tolerate a wide range of resistance shift due to temperature, humidity, or even drift over time.
These resistors are used in:
KWKs anti–surge resistors offer benefits of non-inductive performance and high-power density. As an added feature, they provide impulse energy capability normally associated with wire-wound or composition resistors. KWK anti–surge resistors can handle voltages of up to 1200V and does not need any additional protective measures.
The KCBR series of anti–surge wire-wound resistors from KWK are capable of withstanding very high pulses.Read Less
