Hi all,
I'm about to place an order with Digi-Key for a bunch of components for the power supply I'm building. (The project is from the TAB guide to understanding electricity and electronics; if you "Search Inside" for "assembly and testing", you can find the description of the project's various stages.)
Right now my order is about 20 bucks. There is a 5 dollar handling fee for orders below $25, so I'm planning to flesh out the order with a few extra goodies.
One potential problem I foresee is that the slightly higher melting temperature of the lead-free solder I use, coupled with my inexperience at soldering, gives a higher probability of damaging sensitive semiconducting components, like my 2SA/2SC transistor pair. I am already determined to use lead-free solder for a variety of reasons which I'd be happy to go into.
So my question is: which heatsinks on Digi-Key's catalog should I order? The specific transistors I'm ordering are the TIP31C, TIP32C, 2SA1943 (replacement for 2SA1302), and 2SC5200 (replacement for 2SC3281). Any pointers you can give me would be much appreciated!
