I have never worked with SMD items before and am a little confused about which items I need to order. For example a resistor marked R010 which was about 3.1mm x 6.2mm and is a 2512. Looking at charts I've seen this resistor listed as .5w, 1w and 2w so I have no idea what wattage is needed b/c not only do the charts list it as different wattages, the items for sale list different wattages.


The items are for building an arduino centered home power monitor
Here is a parts list for one unit but I'm going to need enough for 4-5 of them. The number on the left is the quantity needed for each unit.

(6) 10u C-USC0805 C0805
(8) 100 R-US_M0805 M0805
(16) 10k R-US_M0805 M0805
(1) 330u CPOL-USE3.5-8 E3,5-8
(1) 2200u CPOL-USE5-13 E5-13
(8) AUDIO-JACKSMT SJ-3523-SMT-JACK
(1) SCHOTTKY-DIODE SOD123FL
(4) (Jumper pins??) PINHD-1X2 1X02
LM2575 LM2575 TO263-5
(1) (Jumper Pins??) PINHD-1X25MM_TERMINAL 5MM_TERMINAL
330u L-US6000-XXX-RC 6000-XXXX-RC
EI30-1 EI30-1 (transformer - 120v -> 5v)
HD04-RECTIFIER HD04-RECTIFIER MINIDIP-4

This device is supposed to convert 240 (or 120v) down to 5v for the arduino but I'm thinking I might skip that part and power it directly from a 5v (1.5a) charger which I would think would be sufficient.

Can anyone help me figuring out what SMD parts I need?

The first 5 are the ones I have questions about.
10uf 0805 form? what voltage?
100ohm resistor M0805 what wattage??
10K ohm resistor M0805 what wattage?

 

The nomenclature is terse and abbreviated in a way that suggests it's specific to a library such as Easy EDA uses. If you know the source, you can look for the long description there.

You can make assumptions that resistors of a given package size will all have adequate wattage ratings for the circuit but it would be more prudent to make a determination based on an analysis of the schematic. The same principles apply to the voltage ratings for the capacitors.

A 10μF electrolytic capacitor of that size is going to be tantalum but I couldn't tell you the voltage without looking it up. The 330μF and 2200μF capacitors are aluminum electrolytics.
