FT37-43 Ferrite Toroid – Fair Rite

FT37-43 Ferrite Toroid Core

Material: Type 43 | Outer Diameter: 9.5 mm | Broadband RF & EMI Suppression Core

The FT37-43 is a Type 43 ferrite toroidal core made from high-permeability manganese-zinc (MnZn) ferrite, optimized for broadband RF transformers and EMI suppression in the 1 MHz to 50 MHz frequency range. Compact in size yet effective in performance, it is well-suited for use in QRP baluns, chokes, low-power RF coupling, and filter circuits.

✅ Key Features:

1. Type 43 Ferrite Material (Broadband MnZn)

  • High initial permeability (~850 μi) suitable for RF broadband applications.

  • Delivers effective common-mode noise suppression and transformer coupling from HF to lower VHF bands.

2. Miniature Footprint

  • Small 9.5 mm outer diameter makes it ideal for compact circuits, printed circuit boards (PCBs), and portable antenna systems.

3. Effective Broadband Impedance

  • Typically provides 100–250 ohms impedance in the 10–30 MHz range with proper winding, offering effective RF choking performance in QRP systems.

4. Low Loss & Temperature Stability

  • Maintains magnetic properties across a wide temperature range (-55°C to +125°C), with minimal drift under moderate thermal conditions.
