These devices can also be used as common-mode chokes, as the windings have a 1:1 ratio. They are ideal for applications requiring low profile compact components in a surface mount package. Box All specifications typical at TA=25°C 1 When connecting windings in series, inductance will be 4 times the figure shown. 2 With windings connected in parallel. Maximum DC current occurs when the temperature rise reaches 55°C. 3 For further information, please visit www.murata-ps.com/rohs For full details go to www.murata-ps.com/rohs www.murata-ps.com Technical enquiries - email: mk@murata-ps.com, tel: +44 (0)1908 615232 KMP_4300C_A01 Page 1 of 3 4300 Series Dual Winding Toroidal Surface Mount Inductors INDUCTANCE Vs CURRENT 10 Inductance, L (μH) 43402C 43212C 1 0.001 0.01 0.1 1 10 100 Current, IDC (A) TEMPERATURE Vs CURRENT 60 Temperature rise above ambient, t (ºC) 43402C 50 43212C 40 30 20 10 0 0 2 4 6 8 10 12 14 16 18 20 Current, IDC (A) INDUCTANCE Vs FREQUENCY 10 Inductance, L (μH) 43402C 43212C 1 10 100 1000 10000 Frequency, (kHz) www.murata-ps.com Technical enquiries - email: mk@murata-ps.com, tel: +44 (0)1908 615232 KMP_4300C_A01 Page 2 of 3 4300 Series Dual Winding Toroidal Surface Mount Inductors PACKAGE SPECIFICATIONS MECHANICAL DIMENSIONS See Selection Guide for dimensions.
