High-inductance Nanocrystalline Magnetic Core

This core delivers high magnetic permeability, low insertion loss, and excellent frequency response, along with a high Curie temperature (580°C) and outstanding temperature stability—inductance remains virtually constant from –55°C to 125°C. Ideal for EMC common-mode choke cores and miniature isolation transformers, it ensures reliable performance in high‑density, noise‑sensitive power applications.
