The FT82-43 is a high-quality Type 43 manganese-zinc (MnZn) ferrite toroid, engineered for use in RF broadband transformers, baluns, and common-mode chokes. With a larger size than FT50 or FT37 cores, the FT82-43 provides higher power handling, greater inductance, and better impedance transformation in the 1 MHz to 50 MHz range.
It is a popular choice for QRO HF antenna systems, noise suppression, and EMI/RFI control, suitable for both amateur and commercial RF applications.
