Pinouts, Package Changes and Subs

With so many components on allocation, having extended lead times or simply not available, minor re-design is the popular task of the day. MCUs can often be replaced with another family member and most passives and power components have options... Read more

Scam alert in the components world

As if there aren't enough challenges for all of us right now, we have been receiving reports of scammers impersonating legitimate component suppliers. They claim to have hard to get parts available, but just take your money and give nothing... Read more
