An integral part of Pack LitzWire's philosophy is the ongoing progress of our Litz Wire technology. New applications of the HF-Litz Wire open up opportunities of performance optimization. However, this also increases the demands on the Litz Wire and its production. Aspects such as thermal impact or the consequences of aging processes on performance are intensively studied in collaboration with universities and customers. The insights gained from this are implemented in production and directly into the advice of the Litz Wire design for the components of our customers.
