34 AWG wire (0.1601 mm diameter) is used in precision electromagnetic coils, small transformer windings, and inductor cores. It is common in RFID antenna coils, small stepper motor windings, and telephone receiver speakers. At this gauge, the wire is fragile and typically wound by machine.
34 AWG wire has a diameter of 0.1601 mm (160.1 µm), which is roughly 2.3× the thickness of a human hair (about 0.07 mm). Its cross-sectional area is just 0.020142 mm². At this size, the wire is too fragile for manual handling in most cases and is typically wound by machine as enameled magnet wire.
