Electronic Symbols

Open-Source electronic schematic diagram symbols in SVG, JPG, and PNG formats.

About

Each component was drawn as vector shapes, on individual 150x150 tiles. Each path is (mostly) aligned with a 25px grid with 4 sub-divisions. This should make the outbound leads easier to connect in-between components.

The available formats are:

  • SVG - Has been optimized with SVGO for smaller filesizes.
  • PNG - Transparent background with black outlines on top.
  • JPG - Black on white, compressed to 80% quality.

Additionally there is a JPG-ICO folder which holds 32x32 50% quality jpg versions for this table.

Manifest

There is a manifest.json file available that lists all the components available with unique id's, categories, filename, standards, etc.. It is presented as a JSON array. The following typescript type can be used to describe the listings

enum ComponentStandard {
  Common = "COMMON",
  IEEE = "IEEE",
  IEC = "IEC",
};

interface Component {
  id: string;
  name: string;
  category: string;
  subCategory?: string;
  standard: ComponentStandard;
  filename: string;
};
type ComponentManifest = Array<Component>;
