Ultra Librarian

CAD libraries are an integral part of the PCB design process. Unfortunately, engineers are often forced to spend too much time with creating their own symbols, footprints, and 3D models from scratch. The time it takes for engineers to add new components to a design slows down project timelines, causing delays and missed milestones. Existing starter library solutions with small, static libraries may help to initially make progress on a design; however, they are never large enough to be truly useful, nor are they updated with the latest parts to meet designers’ needs.

You are looking for a new part? Ultra Librarian offers symbols, footprints, 3D models and often also simulation models and reference designs for parts in nearly any CAD format. You can easily evaluate the part and make your selection based on positive simulation results.

Ultra Librarian provides a comprehensive library of millions of components eliminating the need for manual building and maintenance. Ultra Librarian offers search, preview and place components quickly without leaving the native CAD design environment saving time and eliminating errors.

All major CAD tools are supported, which engineers and PCB designer are using today. The list is long: Altium, Allegro, Autodesk Fusion 360, Cadence, Cadstar, CR-5000, CR-8000, Eagle, KiCad, Mentor Graphics, OrCAD, PADs, Pulsonix, Quadcept, Siemens, Target 3001!, Xpedition, and more


  • Access to a continuoulsy growing library of validated parts with over 16 million parts
  • Reduce the burden on engineers to build and maintain your PCB libraries so they can focus on design work
  • Easily search for and place components directly into CAD design environment
  • Unified library of symbols, footprints, and 3D models, automatically linked to the elements of the part as a single component
  • Support of 24 tools / 32 different CAD formats
FREE Symbols, Footprints, and 3D Models for Nearly All CAD Tools



Schematic Symbols

Ultra Librarian symbols are built based on the ANSI Y32.2-1975 (Reaffirmed 1989) standard. By default, symbols are entered numerically by pin number, not arranged by function. However, users can auto-partition using the Online Reader or the desktop software. Users using the Ultra Librarian Silver and Gold software have access to easy to use, manual pin arrangement tools if a unique presentation is required.


PCB Footprints

When using metric measurements, parts are consistent with IPC-7351B standard. However, components built in English units (UL default measurement system), deviate from this standard in naming conventions. Where possible the naming referred to in the IPC-7351B is used, with the exception that sizes are in mils rather than millimeter. An example might be CC1206 for a chip capacitor that is 120 mils by 60 mils. If such is not obvious then a two or three letter designator is assigned (or the standard designator used on PCB silkscreens) such as RES, CAP, FUS, etc.

3D Step Models

All 3D models in the library are built to STEP-file format, ISO 10303-21. Since 3D models are dynamically created from footprint information, rotation, origin, and pins are going to be the same as the original footprint – no need to mate the two. 3D models are shape-based and export to .STL and STEP formats most accurately. All 3D models are only able to be created from footprints that are built using UL template system, which means about 85 % of footprints are covered by 3D models.

OMNYA Integration

With the OMNYA Integration Platform engineers have direct access from their OrCAD Capture to the resources with many million manufacturing parts at Ultra Librarian. After looking for a new part using the component distributors data base, the information for schematic symbols, or footprints is only one more click away. This tight integration enables real-time selection of parts and suitable alternate parts to prepare for possible obsolescence.
