## **ABSOLUTE MAXIMUM RATINGS** 

Operating temperature range -40°C to +125°C Storage temperature range -40°C to +150°C 

~~|~~ **SOLDERING INFORMATION[3]** Peak reflow temperature 245°C Pin finish Matte tin Moisture sensitivity level 1 

**PACKAGING INFORMATION** ~~Co~~ Tape & 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 65% (tolerance ±30%) or 75% 

- (tolerance: ±20%) of its nominal 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 nominal value. 

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

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