The Percolation Phenomenon: The Silent Factor in Inductor Reliability

Designing with DC/DC converters often means relying on molded inductors for their small footprint and ability to withstand harsh environments. However, higher electrical and thermal stresses can gradually increase magnetic core loss due to insulation breakdown within the core material. In this episode, we explain the percolation phenomenon, Würth Elektronik's approach to understanding insulation degradation in molded inductors, and what it means for the long-term performance of your designs.  To view the datasheets or order samples, visit Würth Elektronik online or visit the MyWE customer portal.
