FT240-61 Ferrite Core (Material #61)

The FT240-61 is a large ferrite toroid made from material #61, engineered for low-loss performance into the VHF and UHF spectrum. It’s well suited for broadband transformers, matching networks, and RF chokes where 100–500 MHz coverage is required.

Specifications
  • Material: #61 ferrite mix
  • Outer diameter: 61 mm
  • Inner diameter: 35 mm
  • Thickness: 13 mm
  • Weight: ~120 g
  • Frequency range: 100 MHz – 500 MHz

Typical Applications

  • Broadband VHF/UHF baluns and transformers
  • High-frequency EMI/RFI suppression
  • Low-loss inductors for RF design labs
  • Stacked cores for higher power in repeater or contest environments

For HF common-mode chokes, mixes 31 or 43 are usually better suited. Mix 61 excels in the upper HF, VHF, and UHF ranges where low loss is key.
