The integral ferrite shield makes these devices ideal for protecting circuits susceptible to EMI. Operating free air temperature range -40°C to +85°C Storage temperature range -40°C to 125°C SOLDERING INFORMATION2 Peak wave solder temperature 260˚C for 10 seconds Pin finish Matte tin All specifications typical at TA=25°C 1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40°C, whichever is sooner. 2 For further information, please visit www.murata-ps.com/rohs For lower current versions with the same footprint see our 1200LRS Series.
