Hello Jonatan
I have an old sample box (more than 10 years) of Wurth coils and I used them. It may happen they are already obsolete :)
Similar coils you can get at any bigger parts supplier (Mouser, Digikey, Farnell, etc), ebay or Chinese part suppliers.?
Link example:
I prefer to choose wire wound inductors (usually better Q, looks like little tantalum capacitors - like in my case - or you can even see the windings), not multilayer (higher resistance, lower self resonance frequency, looks like ceramic capacitor). Not saying multilayer is a crap, you just need to know where it can be used and where is better to get something better :)
