  • Breaking 7805 Pins

    Im having difficulty keeping the 7805 regulator in working condition. is there some sort of connector or something that slides over it to keep this from happening?

    Are you breaking the pins or burning it out?

          i guess im being to rough with the unit itself. the first time i broke it when soldering on the wires, 2nd time i broke it off when placing the unit

            I guess be more careful

            I have used many 7805 in my days. Sometimes on board, sometimes not. Never had an issue breaking any pins, especially when soldering to the leads. THat doesn't seem like a time for them to break.

              Yeah that is really strange, I mean I know they don't like to be bent that much, but they should survive at least 6 or 7 bends before they even think about breaking.

                  are they breaking at the base of the the ceramic or is there some lead left? I'm just trying to get an idea of how you could be breaking these things.

                    The only thing I can think of is that he is using a 250 watt Soldering gun, and it is breaking at the ceramic. Nothing else really makes sense unless and until the OP tells us/shows us more.

                      A 3 pin computer fan connector will work.

                      Let me guess, these 7805s are from Radio Shack. I had one from there that a lead broke off at the ceramic, from being bent only 4 times without heat.

                        yea they are the ones from radioshack. ill try and get a pic of them later. essentially the pin breaks right where it connects to the plastic part.

                          are you soldering the component to a PCB or is it just floating? If floating, then you may want to solder wires onto the leads then fasten the wires to the comonent's package with a zip-tie, shrink-wrap, or something. This will act as a stress relief for the pins.

                          If you are mounting to a PCB then try lowering your temp and don't manipulate the thing so much

                          I hope you aren't using radioshack solder too. I used some of that stuff before and I think it was 100% tin and barely had any rosin. I think you need the "high-tech" solder from them if you want any lead
