E-Cigarettes

E-cigarettes are electronic devices designed to mimic traditional cigarettes, featuring identical appearance, vapor, flavor and tactile sensation. They mainly consist of four components: e-liquid (containing nicotine, flavorings, propylene glycol and other solvents), heating assembly, power supply and filter. Through heating and atomization, they generate scented aerosol for users to inhale.

MOSFETs are widely adopted in e-cigarettes for temperature control, driving heating coils and performing circuit switching protection.
