3.1uH Air-Core RF Inductor Coil
$7.99
Single air-core RF inductor coil measuring 3.1uH with 0.12 ohm DCR continuity reading. This open-wound coil style is useful for RF circuits, vintage radio repair, ham radio projects, CB radio repair, receiver work, transmitter circuits, filter networks, tuning circuits, oscillator sections, antenna matching projects, experimental RF builds, and general electronics bench stock. The coil has visible wound construction with through-hole lead ends for installation or restoration use.
Historical Note:
Air-core RF coils and inductors have been used for decades in radio receivers, transmitters, filters, oscillators, antenna circuits, matching networks, tuners, and communications equipment. Salvaged and surplus coils like this are useful for technicians, ham operators, CB repair benches, experimenters, and vintage electronics restorers who need real RF parts for repair or circuit work.
