The REOhm resistors are characterised by a high degree of functional safety and a long life.
The resistor wires are wound on a frame and enscapsulated. This provides a very high degree of mechanical protection and no susceptibility to vibrations and oscillations.This construction enables the resistor to absorb higher pulse loads and store them temporarily. External environmental influences have only a marginal affect on resistors, i.e. they are less sensitive to moisture and fouling.
An added benefit of profile resistors is that they have very low levels of audible noise.
