Introduction to Unshielded Inductors
Unshielded inductors, also known as open - core inductors, are passive electronic components that store energy in a magnetic field when an electric current passes through them. Unlike shielded inductors, which have a magnetic shield to contain the magnetic field, unshielded inductors have an open magnetic circuit. This characteristic makes them more cost - effective and suitable for applications where magnetic interference is not a major concern. They are widely used in power supplies, audio circuits, and various electronic devices due to their simplicity and relatively low cost.
