T30-3 - Iron powder toroid core, 0.02 - 1 MHz, OD 7.8 mm

Iron Powder Toroid T30-3 Micrometals

The T30-3 toroid from Micrometals is an iron powder magnetic core designed for low-frequency RF applications. Thanks to its Mix 3 and initial permeability of 35, this toroid is particularly suitable for circuits requiring high stability and signal handling precision.

The T30-3 is ideal for building inductors, broadband transformers, low-pass filters and impedance matching circuits. It is commonly used in amateur radio, analog and digital communication systems, and power electronics projects requiring stable response up to 1 MHz.

Mix 3 offers high linearity and low magnetic loss, making this toroid ideal for applications where maintaining a high Q (quality factor) and reducing signal distortion is essential.

Typical Applications of the T30-3 Toroid

• Broadband RF transformers
• Inductors for low-pass filters
• Compensation coils for audio circuits
• DC-DC converters and switching regulators
• Amateur radio and SDR (Software Defined Radio) projects
• EMI/RFI filters for noise suppression
