Winding is good - Folding is better!
Foldflex technology: Innovative solutions with embedded passive components for customized applications.
Miniaturization is also proceeding rapidly in the area of inductive components and increasingly challenges manufacturers to find new solutions.
With Foldflex technology, Würth Elektronik has developed a new procedure for folding flexible foil structures in order to embed coils with almost any number of layers, high current loading capacity, and low parasitic capacities into circuit boards.
Coils and inductors based on multilayer circuit boards offer a compact and robust solution. The coil can be fitted mechanically and can be used in numerous applications, e.g. as a power supply for LED applications.

The advantages of this technology are persuasive:
- Outstanding power density
- Thermal loading capacity
- Increased integration density
- Mechanical stability to resist vibrations and acceleration
- Excellent reproducibility in terms of production tolerances
- Shortening of time-to-market
Wide variety of possible applications for the Faltflex technology:
- Non-contact charger
- Adjustable camera positioning
- Power system for micromotors
- Piezo electric current generator
- RFID tags / receiver modules
Soldering is good – embedding is better!
Miniaturisation does not stop at power electronics but calls for the development of more compact power supplies.
Würth Elektronik has the solution: Embedded Multilayer Inductances or embedded transformers which allow the overall height to be reduced to a minimum while increasing heat dissipation. Inductances embedded on a multilayer basis are suitable for small and medium output ranges and can be customised to your individul requirements.
