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 specifi cations typical at T=25°C 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 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 (cid:3) (cid:3) For full details go to www.murata-ps.com/rohs www.murata-ps.com/support KMP_3700C_A02 Page 1 of 3
