Molding Power Inductors – HEI Series
HEI Series
The HEI 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
RoHS, Halogen Free and REACH Compliance
High Efficiency
Excellent Q, RDC and saturation current
Low profile and miniature size down to 1.6*0.8*0.8mm
Applications
Smartphones, tablets and wearable devices
HDD, SSD and PC peripheral devices
DSC, camcorders
PND
DC/DC converters
