Tubular high-voltage resistors

Description

Metallux 968 and 969 tubular high-voltage resistors are designed for demanding applications requiring high operating voltages, high resistance values and reliable performance. Their thick film technology and robust ceramic rod design provide high electrical stability and low inductance, even under demanding environmental conditions.

The tubular design is particularly suitable for high-voltage and high-power applications where electrical stability and low inductance are required. When selecting a tubular resistor, key parameters include operating voltage, resistance value, power rating, voltage coefficient, temperature coefficient and tolerance.

Our portfolio includes HVR, HPR, HVI impulse and HVD divider series, covering different requirements for high-voltage applications.

In addition to our standard portfolio, Metallux develops custom tubular high-voltage resistors tailored to specific electrical and mechanical requirements.
