Molding Power Inductors – HEI Series
HEI Series
Features
High Efficiency
Small Sizes in 2.0*1.2*1.0mm
High Saturated Current
High Q / Low Rac
Low Rdc
Product Identification
Power inductor takes an important part in the efficiency performance
of DC/DC converter, and HEI products is designed to take care of
both PFM and PWM application performance. Therefore, for HEI
product, the Q(Rac) value at light load and the RDC value at heavy
load are both superior to other competitors. Furthermore, the
saturated current performance is also great, so it helps to get the
ripple current lower and enhance the efficiency result.
