so many resistors!

Like I said before, anything rated above 10V and +/- 10% tolerance will be fine.

oh, oops sorry i missed your other post

in the series column it says either TAJ or TPS which one?

BTW how do you pay for stuff on digikey? paypal, or credit card?

It really shouldn't matter if you choose TAJ or TPS. However, on the data sheet for the TPS, it says they have been optimized for power supply applications. Also on the data sheet is a picture of a PS2 controller; don't ask me why but maybe it is a good omen (or a bad one, considering you are building a portable Nintendo). The TPS are a bit more expensive, but if you are only buying a few, $3 versus $1 is not a big deal.

As far as payment, Digikey doesn't accept Paypal (I think). So use a credit card or a debit card.

so is TPS better?

Really, it shouldn't matter. TPS is "optimized" for power source applications. If you are going to get an IRU120633, then use the follwoing capacitor

478-1762-1-ND (this is the Digikey part #).

This has an ESR (equivalent series resistance) falling in line with the manufacturers recommendations and is about 6mm long (as opposed to some of the others which are around 3mm) which will make it a little easier to work with if you are welding by hand. Since they are cheap (88 cents a pop) buy 5 or 10 so that if you mess up you have a backup.

should this diagram work?

rawls · Post by **rawls** » Wed Jun 29, 2005 4:04 pm

Yeah, that'll work. However, there is a "ground" tab on the 1206 that must be connected to ground (you should probably solder it to a grounded heatsink so that any heat problems will be mitigated).

thanks very much rawls, you're awsome. i fixed my diagram so now it should be fine

Microfarad with Mu is "µF", because Mu is "µ".

It comes out as ÂµF.
