So do you think this: Elektroniikan verkkokauppa ja myymälä Vantaalla - PARTCO can be good for me? And if I use that have I use heat sinks?
Yes, I think the IRL540 will work without a heat sink It will be dissipating at least 750mW though, so it might get warm (~75C) but it shouldn't melt anything. Is there any ventilation? Is it in a warm environment, like anything above room temperature?
