Heat Sinkable Resistors
Much smaller than standard parts of the same wattage, Heatsinkable power resistors release their heat in one plane. The single side is attached to a heatsink and the heat generated is absorbed. Once the heat is absorbed it is released into the air through the heatsink. Although much smaller, they require the use of a heatsink to achieve the wattage advertised. The mass required by adding a heatsink power resistor is often similar to that of a resistor designed for use without the aid of a heatsink.
