Symbol Libraries

An unofficial collection of schematic symbols for KiCad 6.

Atomic Parts

All parts are "atomic" — they have a "fully-specified" symbol and an associated footprint. The footprints are created directly from the manufacturer's specifications and are located in the kicad-unofficial/footprints repository.

Because the symbols are fully-specified, they each represent a specific part that can be ordered from a supplier. Furthermore, they work out-of-the-box with the Octopart BOM generator. An Octopart Query field is included where necessary.

Generic symbols are also provided for parts that are available in more than one package (always alongside the fully-specified symbols), and in some other special cases.

For more information about "atomic" parts, "fully-specified" symbols and "generic" symbols, please see the KiCad Library Conventions.

Automotive Qualified Parts

Automotive qualified parts (AEC-Q100, etc) are marked with a 🚗 (car icon) in the symbol index below.

The keyword automotive can be used to find these symbols within KiCad.

Enclosures

Some symbols represent PCB enclosures rather than parts to be placed on the PCB. They are marked with a 📦 (package icon) in the symbol index below.

Enclosure footprints define the edge cuts layer (PCB shape) and mounting holes.

Symbol Index

This is an index of the available libraries and the symbols they contain. Each library contains symbols for a specific vendor or manufacturer.

Notes for Symbol Creators

• Name the component as the part number used for ordering, excluding packing alternatives.
• Start the description with the "general" part number (usually the one used to identify the datasheet).
• Prefer symbols that are easy to layout in schematics over symbols that match pin layouts.
• End the description with the package name, if multiple are available.
• Use a border of 0.254mm on filled shapes
• Link directly to manufacturer's datasheet (not Mouser, for example)
• Include an Octopart Query field, wherever possible
• For automotive qualified parts:
  • Include automotive and aec keywords
  • Include automotive qualified in the description
