Accurate components for your PCB Parts

3d step models

Finding 3D models for the components in your PCB can be a daunting task. Even if models exist they may not be in formats your PCB tool can accept or are not in synch with your existing PCB footprints requiring manual orientation and checking.

Prevent fit errors, perform early thermal analysis, and view your design in realistic 3D before a single prototype is built with 3D models from Ultra Librarian. Examples of 3D models available for download include:

Bel Fuse Inc. Fuse Clips: FC -203 BRIGHT TIN

Diodes Inc. Standard Diode: 1N4148W-7-F

Fairchild Semiconductor Regulator: LM7805CT

Stackpole Inc. Carbon Film Resistors: CF14JT10K0

Texas Instruments Bipolar Array Transistor: ULN2803ADWR
