Fucking max ratings, how do it work???
I'm always confused on how absolute max ratings like power or current are determined. For example:
DO-41 (glass) zeners are all rated for 1W, can you really run them >150 C for any appreciable amount of time?

Furthermore, I'll notice often on opamps, they list say +-22V, with indefinite short current of 25mA, but they almost always say "don't do this -> damage to device". Why would they have chosen that limit value then, vs say 10mA (eg. Pd < 500mW worst case). Not to mention, these specs seemingly stay unchanged if they port to a dual/quad package. idk its annoying

other than some sketchy hardware that I cannot recommend(really ass dip/sip sockets, tiny ass headers w/ 50% chance of no connect, etc) they are a godsend for anything discrete or old schoolish IC (cheep 2). I was able to custom pick maybe 5000 1% resistors while still cheaper than chink-bay kits.
