Not necessarily *different* package - usually just bigger.I think it is 3 watt, when you get to 5 watts they put it in a different package don't they?
I screwed up by ordering a R15 resistor, not 0R15 that was my question, R15 is different than 0.15 ohm..
The one I ordered just has R15 3W stamped on it. I'll double check when I get home but am prepared to order one that says 0.15 @ 3W
