I have a selection of common-ish values of components I use in my designs.
I also have four values of ceramic multilayer capacitors I use2.
For simplicity sake, I will at some point reduce the number of values I use further, but in the interim here is a list of common passive SMD components in different SMD sizes that I hold in stock with a link to a few suppliers, I mostly use a mixture of Farnell and LCSC.
|Imperial [metric] (power dissipation)||0603  (1/16 W)||0805  (1/10W)||1206  (1/8W)||2512  (1/4W)||1/4 W Though hole|
|Dimensions (approx mm).||1.5 x 0.9||2 x 1.2||3.2 x 1.6||6.3 x 3.2||length 6.5 ± 0.5|
|Land Pattern3.||a = 0.9|
b = 0.6
c = 0.9
|a = 1.3|
b = 0.7
c = 1.2
|a = 1.6|
b = 0.9
c = 2.0
|a = 3.5|
b = 1.6
c = 3.8

I use Würth Elektronik ferrite beads in my designs.
I have a set of each of the WE-CBF design kits, There are two kits available, a small size ferrite kit (WE# 742-790) that contains 0402, 0603, 0805 sized ferrites. And the WE-CBF Large Size (WE# 742-791) that contains 1206, 1210, 1806, and 1812 sized ferrites.
It is easier to design 0 ohm resistors in place before taking a design to an EMC lab, and if there are issues that could benefit from additional filtering, these resistors can be swapped with a ferrite bead with less effort than clearing solder resist, cutting a track and trying to insert a bead.
- Electronic Things also sell an Electrolytic Surface Mount Capacitor Starter Pack and other components
- yes I am aware of the myth of three capacitor values
- you may have better luck with different dimensions
- Allows me to have non populate pads for adding filtering components if needed them at a later date
- For use as shunts
- Contains 20 Ω
