Tubular Resistors; Vitreous Enamelled

Vitreous Wirewound Power Resistors are traditional Danotherm products that have been produced since the 1940’s.

These are all welded, wound on Steatite C221 and the wires are protected by a vitreous enamel. The climate category meets  IEC 68-2-3 Ca. 56 days, 93 % RH.

The resistors have a standard 6mm creepage distance but can be customer specified to meet any voltage level.
