Resistor Wattage? Capacitor Voltage?

Post by chris » Mon May 09, 2016 2:58 pm

Another question about the resistors and capacitors.

I see listings for resistors listed as 1/2 watt (http://www.ebay.com/itm/100-x-150-Ohm-C ... SwfcVUJCdn) and 1/4 watt (http://www.ebay.com/itm/100-x-Resistors ... SwEeFVUF7p) and more... does that really make a difference?

Same for capacitors, except differing voltage? 100V http://www.ebay.com/itm/10-x-33nF-0-033 ... XQTT9RzKEN and 400V http://www.ebay.com/itm/10Pcs-0-033uF-3 ... xyaTxTRFc1

Does one make a difference over another? Thanks.

1/4 w will be enough, but they really don't make a difference :)

400V is more than enough for a capacitor voltage. :)

Does anybody know the capacitor used in the game SD card conversion? I know it 1uf but there seems to be different voltages?

Please help :)

The voltage rating on capacitors is the maximum voltage that the capacitor can safely handle. Since SD cards use very low voltage (only 3.3 volts), you don't have to worry about that. You could buy a 50v capacitor, a 100v capacitor, a 400v capacitor, they should all work.
