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 Applications  High Efficiency  Small Sizes in 2.0*1.2*0.8mm  High Saturated Current  High Q / Low Rac  Low Rdc  Smart phones  Bluetooth Headsets  Tablet PCs  PND  PC peripheral devices  DSC, Camcorders Product Identification Shape and Dimensions Recommended Pattern Dimensions in mm TYPE A B C D Dimensions in mm TYPE A B C 201610A 0.9 2.0 1.6 252010A 1.2 2.8 2.0 252012A 1.2 2.8 2.0 322510A 1.7 3.2 2.5 322512A 1.7 3.2 2.5
