LMI Series
Moiding power lnducto rs
The LEI Series is designed specifically to enhance both PFM and
PWM application performance.Q(Rac) value at light load and the
RDC value at heavy load are both exceptional. Furthermore, the
saturated current performance is also optimal, helping to reduce the
ripple current and enhance the efficiency.
Features
Applications
