They are ideally suited for use where high current and low loss is essential, such as in laptop computers and plasma screens. Moisture sensitivity level 1 PACKAGING INFORMATION Tape & Reel Height A Height B 700 per reel 550 per reel All specifications typical at TA=25°C 1 The maximum DC Current is the value at which the inductance falls to 80% of its zero current value, or when its temperature rise reaches 40°C, whichever is sooner. 2 Saturation current is the continuous current at 20°C ambient at which the inductance falls to 80% of its zero current value. 3 For further information, please visit www.murata-ps.com/rohs For full details go to www.murata-ps.com/rohs www.murata-ps.com/support KMP_3700C_A02 Page 1 of 3 3700 Series Flat Coil SM Power Inductors INDUCTANCE Vs CURRENT 10 Inductance, L (μH) 3.9μH 2.4μH 1.4μH 0.95μH 1 0.3μH 0.1 0.1 1 10 100 Current, IDC (A) TEMPERATURE Vs CURRENT Temperature rise above ambient, t (ºC) 50 3.9μH 2.4μH 1.4μH 0.95μH 0.3μH 40 30 20 10 0 0 5 10 15 20 25 30 Current, IDC (A) www.murata-ps.com/support KMP_3700C_A02 Page 2 of 3 3700 Series Flat Coil SM Power Inductors PACKAGE SPECIFICATIONS MECHANICAL DIMENSIONS RECOMMENDED FOOTPRINT DETAILS 14.5 (0.571) Max. 37XXXC XYYWW 12.8 (0.504) 7.5±1.5 (0.295±0.059) 11.5 (0.453) Max.
