For low to medium rated power (1W...8W), VITROHM offers wirewound resistors, which are coated with a special silicone-varnish that withstands temperatures of 350°C continously.
Axial and radial styles are available.
Series CRF is designed for safety applications, connected to mains-voltage.

For medium to high rated power (4W...40W), resistors are mounted in a ceramic case, which also provides full electrical insulation.
Axial, radial and vertical styles are available.
Series KT and KF additionally provide a thermofuse, which will interrupt circuit in case of electrical overload.

For many electronic applications (switch controllers, switch-mode power-supplies, frequency converters) induction-free resistors featuring very low ohmic values are needed.
VITROHM offers in it´s today´s programme a resistance range from 0R0005 to 3R3 and power ratings fro 1 W to 10 W in several styles.

Base-metals like Tantalum and Tungsten (RG/RGU, metalglaze) and Tinoxide (PO, metaloxide) render performance to these series´ which are hardly found with other filmtechnologies.
RG/ RGU (axial/vertical) with their capless soldered internal contacts and their thick-film elements provide highest reliability even under difficult environmental conditions.
Metaloxide resistors series PO make film technology available to power applicaions because of their wide temperature range and their pulse-capabilities, which are high for film resistors.
Power Metal Film Resistors series PF are from thinfilm technology based on NiChrome-alloys, and offer small sizes, good stability and acceptable pulse-load-capabilities. The price / performance ratio is very good.
