The maximum surface temperature is around 300°C and the TCR is low with around 25 ppm/°C for the ohmic values above 50Ω.
Next to precision, there are also wire wound resistors with high power rating for 50W or more. They are widely used in many power applications; not only are they physically larger than many other types of resistor, but having a wire conductor and a ceramic former, they are for more suited to being a high power resistor than other types more widely found. As a result wire would resistors are used in a number of key areas because of their properties: Wirewould resistors can be used in a variety of different applications and typically these fall into some major categories for which the construction of the resistor may change. For low power ratings, very thin wire is used.
