| What schottky for rectifing 5-9v supply - Click HERE for Original Thread |

Ok get yourself some schottyky`s they said.... There are only 500 different ones!
I`m building a 5 and 9 volt supply for a cd player, using 9v toroids, and a 15v toroid. The maximum current will not exeed 2A
What schottky`s should do the trick? Are there things I should look in to, like ...?
And another question; for the lm317, I have to use resistors, to get to 5 and 9 volt. I`m thinking of using tantaan resistors (is that in english tantal?) does that have ANY bennifits, over using other (metal film?) resistors?
The ordering of some components, gives me a headache!
tnx in advance guys. |

| tantalum resistor are fragile and are not recommended becaus of that. |

Probably not, I really don't see what could be better in a tantalum resistor.
Using good quality metal film resistor is enough.
(IMO they could be worst than standard resistor but this is just my opinion) |

| And the schottky diodes... Which ones should ik use? I have no idea what to look for. |

I use a lot of 1N5822's. They are 3A, 40 volt devices which should be readily available. At 1 A the voltage drop is about .4 volts. I have never had any troubles with them.
I think metal film resistors will be quite adequate. No need to go overboard with an op amp circuit. |
