Questions tagged [packages]
In electronics packages refer to the physical encapsulation of a device. Most package names are standardized, so for example a TO-92 package will have similar dimensions and pin spacing between manufacturers so the same PCB footprint may be used. Be aware however many packages have subtle variations, for example TO-206AA, TO-206AB and TO-206AC.
