Built to the Highest Standards

 

We take part creation very seriously. To help maintain access to consistent and reliable library data, we utilize globally recognized industry standards from IPC-7351B for PCB footprints, ASNI Y32.2-1975 (reaffirmed 1989) for schematic symbols, and ISO10303-21 for 3D STEP models. Learn More

 

Parts must pass the most rigorous verification process in the industry, with over 30 different verification tests prior to being added to our library.
