T25-17 - Iron powder toroid core, 20 - 200 MHz, OD 6.48 mm

Micrometals T25-17 Toroidal Core for RF

Engineered for demanding RF and high-frequency applications, the Micrometals T25-17 toroidal core combines a dimension of 6.48 mm (0.255 inches) with exceptional magnetic stability. Made from proprietary -17 iron powder material, this core offers low permeability and a tightly controlled AL value, ensuring predictable inductance across a wide range of operating conditions. Its robust mechanical design make it a trusted choice for engineers developing broadband transformers, EMI filters, and custom inductors. Whether you're optimizing a VHF balun or designing a high-frequency choke, the T25-17 delivers consistent performance, minimal core loss, and reliable thermal behavior.
