KWX woven resistors are the highest power per weight or volume resistors on the market. They achieve high wattages without the need of a heat sink.The unique design maximizes surface area while minimizing thermal mass,allowing unimpeded convection and radiation away from the resistor surface. 

KWX power resistors are woven with a resistance alloy wire and high temperature yarn to allow high heat dissipation in a slim configuration.They work well in AC, DC or pulsed applications and can carry voltages up to 20kV.Resistor cages are available for mounting resistors in series or parallel.
