Preferred Types. 

This is a part of the website www.breem.nl . 

These datasheet pages come from a private server, so they may load slower than you are used to.

By times they may be unavailable. I'm sorry for that, just try another time.

Back to the Datasheet page,  or to the Home-page (mainly Dutch).      

This page lists preferred types I try to limit myself to in my designs.

Primary criterion is the availability for private people. 
Do not misunderstand: I do not sell these things. Order info is where I buy them. Cnrd = Conrad.  DK = Digi-Key

Before using such a component check at your preferred shops if it is stil available.
