Anti - Surge / Pulse Withstanding

Overview

Anti–Surge/Pulse Withstanding

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 Wound Resistors 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 shifts due to temperature, humidity, or even drift over time.

Anti-surge Resistors Applications are:

  • High-power electronics
  • Transit and overload surge protection
  • In-rush current limiting
  • Automotive industries

Why KWK Anti-Surge / Pulse withstanding Resistors?

KWK’s 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.
