Our Part Professional partners offer a wide range of parts, the passive (capacitors, resistors, inductors) and electromechanical (Crystals, Switches, Connectors) components by Würth Elektronik are complemented by the active (Diodes, Transistors, MOSFETs) components by Diotec.
Both manufacturers offer extensive documentation and tools for component selection such as Appnotes, Reference Designs, Parametric search tools and libraries for PCB design software.
These resources can be used to select components for your application. While it is possible to choose components in our BOM tool, we highly recommend updating the BOM in your PCB project files too.
Specifics about our partners
Würth Elektronik
- Appnotes: Practical application & design notes from electronics experts
- PCB design libraries: Component Libraries from Würth Elektronik
- Redexpert REDEXPERT
Redexpert is a Tool to select and calculate components, for example, we used it in this Circuit Appnote: Selecting Ceramic Capacitors (MLCCs) for Low droput regulators (LDOs)
Parametric search
REDEXPERT for Würth Elektronik and filter by properties your part requires for example the current, voltage, turn-on voltage and footprint of a MOSFET. But be aware that different suppliers may use different names for the same component package, for example MLPAK33/SOT8002-1/PowerFLAT™ 3.3x3.3/Power QFN 3x3.
Diotec
- Selection Guides: Selection Guide
- PCB design libraries: Diotec Parts at SnapEDA
- Appnotes: Application Notes for Diotec products
Cross-Reference Search
Diotec offers a cross-reference search, simply enter the component you currently use, and an alternative component will be displayed if available.
Parametric Search
Diotec also offers parametric search on its website.
