DigiKey Electronics
Electronic components by mail
I see that someone recommended Mouser as a source for electronic components. Digikey offered catalog sales (i.e., as a DIY source) long before Mouser and I have used them since the 1970s. Their product offering is fuller, their search engine works better, and they have better customer support. For example, if you order by 8PM CT, the order will ship later that night and thus can arrive the next morning, something Mouser and Newark cannot match. Most electrical engineers (like me) and DIYers I know check Digikey first.
