The parts are ideal for applications requiring low profile compact components in a surface mount package. Peak reflow temperature 245˚C Pin finish Pure tin dip 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 full details go to www.murata-ps.com/rohs www.murata-ps.com/support KMP_4000C_B03 Page 1 of 2 4000 Series Toroidal Surface Mount Inductors PACKAGE SPECIFICATIONS MECHANICAL DIMENSIONS RECOMMENDED FOOTPRINT DETAILS 14.10 (0.555) Max. 40331C 13.21 (0.520) 14.22 (0.560) Max. 11.68 (0.460) 1.52 (0.060) XYYWW S All dimensions in mm (inches).
