Also having some of these termination resistors ,I see the ones supplied
with a plastic green cap are good for 0.5 Watt . Another one having a
slightly larger diameter and donning a red plastic cap is highly likely
good for 1 Watt ,although the latter is not embossed on the cap
To increase the power rating by using a transistor 'cooling star' is an
excellent idea.
