The 40/70MNJ50R0DE is a heatsinkable, non-inductive wirewound resistor from the Metalohm series, featuring a cold-rolled steel case and radial terminals. It has a resistance of 50 ohms with a 5% tolerance and is rated for 40 watts of power without a heat sink, which increases to 70 watts when properly mounted. This component features a temperature coefficient of 0 ±90ppm/°C and a robust, all-welded, inorganic construction. Its flameproof, nonhygroscopic, and high-surge capabilities make it well-suited for demanding industrial and power electronics applications where reliable power dissipation is critical.
