Iron powder toroid core, 3 - 40 MHz, OD 6.48 mm

Micrometals T25-6 Toroidal Core For RF

The Micrometals T25-6 is a precision-engineered toroidal core made from Mix 6 carbonyl iron powder. With a nominal outer diameter of 6.48mm (0.255 inches), this core is optimized for high-frequency applications requiring low loss and high Q performance. Its stable permeability and compact form factor make it ideal for RF designs where efficiency and consistency are paramount.

Applications

The T25-6 core is widely used in:

• Amateur radio filters
• RF transformers in communication equipment
• Broadband impedance matching networks
• High-Q inductors

Its frequency versatility and mechanical stability make it a trusted choice for both commercial and industrial RF designs.

Advantages

• Low core loss at RF frequencies
• Stable performance across temperature variations
• Excellent for moderate bandwidth designs
