Description
Molding Power Inductors – HEI Series HEI Series
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.
Features
High Efficiency Small Sizes in 2.0*1.2*1.0mm High Saturated Current High Q / Low Rac Low Rdc
Applications
Smart phones Bluetooth Headsets Tablet PCs PND PC peripheral devices DSC, Camcorders
