    Handling and Usage Tips:

    Careful Winding: When winding the wire into coils, it’s essential to do so carefully to avoid damaging the enamel coating, which could lead to short circuits.
    Proper Storage: Store the wire in a dry environment to prevent the insulation from absorbing moisture, which could degrade its performance.
    Soldering: The enamel needs to be stripped off at the ends before soldering to ensure a good electrical connection.
