Hi,
Searching through the forum I found a recent explanation regarding how to choose a voltage for capacitors. I think I'll be fine ordering some 25V capacitors for the led and pic circuits that I'm playing with.
The problem is searching digikey and mouser, I see a wide price range on what appears to be basically the same item. We're not talking a lot of money each, .06-.21 each but when ordering say 50 of each value, and about 8 different values, that can add up and I don't want to waste money on useless parts.
For simple led/4017/pic types of circuits I'm thinking about ordering say 50 each .1µF, 1µF, 4.7µF, 10µF, 22µF, 47µF, 100µF, 220µF. I understand that specific areas of interest will dictate parts and values but does that seem like a decent list of general use capacitors?
I keep coming across parts that I don't have so I'll place another order and try to use the bulk(100 or so) price to get more for less. Below is what I've gathered so far and if there are any other "must have" items that I should order, by all means let me know.
1000 1/4w resistors in different values
10- 40MHZ crystals
5- 20MHZ crystals
25- 32.768 crystals
25- 1000µF 25V aluminum electrolytic capacitors
100- 100µF 10V " "
50- 10µF 25V " "
Single row headers
10- LM723CN programmable regulator
50- 7809CT
10- 2N3055 NPN transistor
100- 2N3906 PNP transistor
100- 2N3904 NPN transistor
100- PN2222ATA NPN transistor
100- 1N5819 Schottky Barrier
100- 1N4007 Rectifier
100- 1N4148-T diode
100- 1N4002 rectifier
100- 1N4001 rectifier
2500 led (I like the lights )
5- 555 timers
25- 4017 decade counter
Misc battery packs
Bag full of potentiometers and a box full of "stuff" from Electronics Goldmine.
4 or 5 different PICs in DIP and you can imagine my dismay when I received the first order from Microchip to realize I had ordered about fifteen 40 pin QFN PICs.
