What is a chassis mount wirewound resistor?

Chassis Mounted resistor is a type of wire wound resistor technology where the ceramic core is wounded with resistance alloys and molded into a aluminium extrusion.

KWK Resistors manufactures Chassis Mount Resistors with non-inductive windings and their compact design is suitable for effective thermal management. Resistance values range from 0.005 ohm up to 250k ohm.
