Unshielded Inductor is an inductive component without additional magnetic shielding structure, whose magnetic field will partially leak into the surrounding environment. The following is a concise explanation of its core features and application scenarios: Key Features: 1) Design without magnetic shielding Without a closed shield around the coil or core, the magnetic field will spread outward and may cause electromagnetic interference (EMI) to neighboring components or circuits. 2)Simple structure and lower cost Eliminates the need for shielding or magnetic adhesive encapsulation, simpler manufacturing process, usually less expensive than shielded inductors. 3) Smaller size Suitable for scenarios where space requirements are high but EMI constraints are relaxed. 4) Thermal performance Open structure may be more conducive to natural heat dissipation, but need to pay attention to the impact of temperature rise on performance.
