The 1K107B nanocrystalline toroidal core (bare core dimensions: 12×8.35×12mm) is optimized for inrush current limiting and power line protection. With exceptional magnetic performance, this core delivers high initial permeability, low core losses, and thermal stability up to 140°C. Its compact structure and reliable inductive behavior make it the ideal magnetic solution for current limiting inductors in high-performance power electronics.
