2.9uH Air-Core RF Inductor Coil
$7.99
Single air-core RF inductor coil measuring 2.9uH with 0.12 ohm DCR continuity reading. This style of open-wound coil is useful for RF circuits, vintage radio repair, ham radio projects, CB radio repair, receiver work, transmitter circuits, filters, tuning networks, experimental RF builds, and general electronics bench stock. The coil has visible wound wire construction with straight lead ends for through-hole installation or restoration use.
Historical Note:
Air-core coils and RF inductors have been used for decades in radios, transmitters, receivers, filters, oscillators, antenna circuits, matching networks, and communications equipment. Salvaged and surplus coils like this are useful for technicians, ham operators, CB repair benches, and vintage electronics restorers who need real RF hardware for repair or experimentation.
