The particularly sturdy power resistor MAL in aluminum housing is loadable up to 250 watts @25°C (with heat-sink - not included) and without heat-sink up to 100 watts @25°C. With its standard resistance range of 0.01Ω..86kΩ (≤ 250kΩ on request), TCR value from ±20ppm/°C and wide resistance tolerance of ±0,01%..± 0%, the resistor is suitable for a wide range of applications. Its numerous options such as low-inductance winding, connection options with 4-pin Kelvin connection or threaded flange as well as commercial versions expand its field by many more applications. MAL resistors are used for current sensing as a shunt resistor or as load resistors. They are suitable for harsh environmental conditions made for excellent power consumption behaviour in a spread temperature range with special demands to a good resistance and tolerance accuracy. Typical applications are power units, converter and inverter circuits and motor control circuits.
