FT140-61 Ferrite Core (Material #61)
The FT140-61 is a mid-sized ferrite toroid made from material #61, designed for low-loss operation in the VHF and UHF spectrum. It’s ideal for compact broadband transformers, baluns, and EMI/RFI suppression from 100–500 MHz.
Specifications
- Material: #61 ferrite mix
- Outer diameter: 35 mm
- Inner diameter: 23 mm
- Thickness: 13 mm
- Weight: ~120 g
- Frequency range: 100 MHz – 500 MHz
Typical Applications
- Compact VHF/UHF baluns and broadband transformers
- Low-loss inductors for RF design projects
- High-frequency EMI/RFI suppression in smaller enclosures
- Portable/low-power RF gear where space is limited
For higher power or HF chokes, larger FT240 cores or lower-frequency mixes (31/43) are better options. Mix 61 shines at 100 MHz and above.
