Performances: Protection class IP54, test voltage 2,5 kV AC, other capacities and mounting dimensions on request

Dimensions in mm

In the event of failure, the resistor becomes high-impedance. Each series is available with a temperature switch. The specified performance values were measured at a horizontal position of the resistors in the air with a distance of min. 100mm to the substrate. The power values refer to the standard products with a normal tolerance of +/- 10% at an ambient temperature of 20°C.
