Custom coil solutions can be developed with guide configurations for manual assembly or surface mount SMD coils for delivery in tape and reel, allowing automated reflow processes for PCBA. Our micro coils can be wound with copper, silver, gold or other wire alloys. Various coatings, overmoulding, packaging and test options are available.

IMPACT OF THE MAGNETIC CORE

The magnetic core is a crucial point for the performance of micro coils. Various materials come into question here. Product Manager Roswitha Ritter gives a brief insight. She is our expert, especially when it comes to miniature coils and sensors for medical technology.
