The rugged MAL series wirewound resistor in an aluminium housing is a power resistor capable of up to 50 Watts at 25 °C (without heatsink). With a choice of resistance range from 0.01 Ω to 250 kΩ, TC value of ±20ppm/°C and wide resistance tolerance of ±0.01% to ±10%, the wirewound resistor covers a wide range of applications. Additional options such as low inductance windings and 4-pole Kelvin connections extend the application range even further.
MAL resistors are used for current measurement as shunt resistors and as load resistors. This is where high power consumption over a wide temperature range places high demands on resistance accuracy and tolerance. Typical applications include converter and inverter circuits, motor control circuits and power supplies.
