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 al so optimal, helping to reduce the ripple current and enhance the efficiency. Features Applications 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 Smartphones, tablets and wearable devices HDD, SSD and PC peripheral devices DSC, camcorders PND DC/DC converters Product Identification Shape and Dimensions Recommended Pattern Dimensions in mm TYPE A B C D 0.3±0.2 0.5±0.3 0.5±0.3 0.5±0.3 0.5±0.3 0.6±0.3 0.6±0.3 0.5±0.3 0.5±0.3 0.5±0.3 Dimensions in mm TYPE A B C 201608A 0.7 2.3 1.8 201610A 0.7 2.3 1.8 252010A 1.2 2.8 2.3 252012A 1.2 2.8 2.3 322510A 1.7 3.5 2.8 322512A 1.7 3.5 2.8 322525A 1.7 3.5 2.8 Moiding power lnducto rs LMI Series L Rev : www.leiditech.com 01.06.2018 1/7 M
