They are ideally suited for use where high current and low loss PACKAGING INFORMATION is essential, such as in laptop computers and Height A Height B plasma screens. Tape & Reel 700 per reel 550 per reel All speci cations typical at T =25C A 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 40C, whichever is sooner. 2 Saturation current is the continuous current at 20C 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 33700 Series Flat Coil SM Power Inductors INDUCTANCE Vs CURRENT 10 3.9H 2.4H 1.4H 0.95H 1 0.3H 0.1 0.1 1 10 100 Current, IDC (A) TEMPERATURE Vs CURRENT 50 3.9H 2.4H 1.4H 0.95H 0.3H 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 Temperature rise above ambient, t (C) Inductance, L ( H)
