- 1 The maximum DC Current is the value at which the inductance falls to 65% (tolerance ±30%) or 75% 

- (tolerance: ±20%) of its zero current value or until its temperature rise reaches 40°C, whichever is sooner. 

- 2 The saturation current is the continuous current at 20°C ambient at which the inductance falls to 65% (tolerance: ±30%) or 75% (tolerance: ±20%) of its zero current value. 

- 3 For further information, please visit www.murata-ps.com/rohs 

- 4 Terminal 3 is open-circuit and for mounting stability only.
