Key Features & Uses:

Material: Type 61 (Nickel-Zinc Ferrite).

Dimensions: ~29mm OD (1.14"), ~19mm ID (0.748"), ~7.5mm Height (0.295").

Applications:

Broadband transformers (HF to 50MHz, up to 200MHz).

High-Q Inductors (0.2-15 MHz).

RF Chokes (RFC).

Noise Suppression (EMI/RFI) at higher frequencies (200MHz-GHz).

Baluns (Balanced/Unbalanced Converters).

Performance: High temperature stability, good for low power, high inductance circuits, and wideband use.
