  • Wattage of this Resistor?

    Can anyone determine the wattage rating on the 8.2ohm resistor in this picture? The dimensions of the body are approx. 9/16" (15mm) long and 3/16" (4.75mm and 5.15mm at the end bumps) wide. I'm thinking it's a 3 (maybe 2) watt, but I'm not sure. Looking at datasheets on DigiKey and comparing is getting sort of tiresome.

    looks like a 1w resistor. could also be a 1/2w resistor. i believe only 1w and 1/2w were made in that type of greyish material. should be able to quickly compare the overall length dimensions of some other resistors of a known wattage to confirm
