The integral ferrite shield makes these devices ideal for protecting circuits susceptible 2 to EMI. SOLDERING INFORMATION Peak wave solder temperature 260C for 10 seconds For higher current versions with the same Matte tin footprint see our 1200RS Series. Pin nish All speci cations typical at T =25C A 1 Maximum DC current occurs when either the inductance falls to 75% of its nominal value or when its temperature rise reaches 40C, 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 1200LRSC A02 Page 1 of 31200LRS Series Through Hole Radial Lead Shielded Inductors INDUCTANCE Vs CURRENT 100000 22mH 6.8mH 10000 680H 1000 68H 100 6.8H 10 1 0.01 0.1 1 10 DC Current, I (A) TEMPERATURE Vs CURRENT 60 68H 6.8H 6.8mH 50 680H 40 30 20 10 0 01 2345 678 Current, IDC (A) INDUCTANCE Vs FREQUENCY 100000 22mH 6.8mH 10000 680H 1000 68H 100 6.8H 10 1 10 100 1000 10000 Frequency, (kHz) www.murata-ps.com/support KMP 1200LRSC A02 Page 2 of 3 Inductance, L ( H) Inductance, L ( H) Temperature rise above ambient, t (C)
