Yootop 20X25mm Ceramic Heatsink Insulator Pad for Transistor Heat Sink TO-3P TO-247 TO-220 Pack of 100

hi I want to talk to you about the lm317 tea this is one of them and something you should know about this chip it gets really really really hot if you put too much voltage into it so the way it works you've got voltage in on this pin this is the adjustment pin and the center pin is the voltage out pin but this connector here is also the voltage out pin so that means that you can get burned more ways than one and be a D check this one this one this one and this one so you can get shocked and you can get earned if there's too much voltage coming in here so the way you avoid both situations is you use a heatsink plus an isolating kit and that's actually what I want to show you is an isolating kit so let's talk about the heatsink heatsink as this is a fairly big one very nice it's got a threaded hole there so you should just be able to screw your IC to it and it will dissipate a lot of heat
