The 1630024-2 is a chassis panel-mount Power Resistor with aluminum housing. The HSC250 10R 5% resistor is a range of extremely stable, high quality wire wound resistor is capable of dissipating high power in a limited space with relatively low surface temperature. The power is rapidly dissipated as heat through the aluminum housing to a specified heat-sink. The resistor is made from quality materials for optimum reliability and stability.
