Magnetic shielding prevents stray magnetic fields from interfering with nearby sensitive components (e.g., sensors, ADCs) and mitigates external field influence on inductor performance. Shielding — typically via core material encapsulation or copper shielding cans — forms a closed magnetic path, substantially reducing leakage flux.
