Inductance values may vary 20%. 2. ETop rated at 150kHz except where designated. 3. ETop rated at 100kHz. 4. SIMPLE SWITCHERTM is a trademark of National Semiconductor Corp. 5. For SMT parts, optional Tape & Reel packaging can be ordered by addin a "T" suffix to the part number (i.e. PE-53801SNL becomes PE-53801SNLT). Pulse complies to industry standard tape and reel specification EIA481. 6. The "NL" suffix indicates an RoHS-compliant part number. Non-NL suffixed parts are not necesssarily RoHS-compliant, but are electrically and mechanically equivalent to NL versions. If a part number does not have the "NL" suffix, but an RoHS compliant version is required, please contact Pulse for availability. 2 Power.PulseElectronics.com 7. 3 The temperature of the component (ambient plus temperature rise) must be within the stated operating temperature range. * Contact Pulse for availability SPM2007_47 (08/20) SMT Power Inductor Toroid - Designed for National's 150kHz Simple SwitcherTM Mechanical LP series PKG A B C D LP-25 .360 9,14 .310 7,87 .250 6,35 .250 6,35 LP-30 .400 10,16 .300 7,62 .300 7,62 .300 7,62 LP-37 .495 12,57 .375 9,52 .375 9,52 .375 9,52 LP-44 .635 16,13 .365 9,27 .500 12,7 .300 7,62 2 D .060 1,52 PE-XXXXX DATE CODE CTRY ORIGIN 1 A MAX .035 0,89 C SUGGESTED PAD LAYOUT A MAX B MAX .135 .010 3,43 0,25 D C 2X LEAD .020 0,51 Mechanical KM Series 3 Power.PulseElectronics.com PKG A B C D E KM-1.0 .340 8,64 .580 14,73 .650 16,51 .290 7,37 .110 2,79 KM-2.0 .450 11,43 .650 16,51 .700 17,73 .325 8,26 .150 3,81 KM-3.0 .450 11,43 .830 21,08 .950 24,13 .415 10,54 .150 3,81 KM-4.0 .610 15,50 .970 24,64 1.10 27,94 .475 12,07 .225 5,72 SPM2007_47 (08/20) SMT Power Inductor Toroid - Designed for National's 150kHz Simple SwitcherTM Mechanical LCI Series PKG A B C D E F LCI-20 .340 8,64 .340 8,64 .270 6,86 .260 6,60 .300 7,62 .270 6,86 LCI-30 .450 11,05 .440 11,18 .360 9,14 .350 8,89 .400 10,16 .360 9,14 LCI-37 .565 14,35 .570 14,48 .360 9,14 .450 11,43 .520 13,21 .460 11,68 LCI-44 .600 15,24 .620 15,75 .390 9,91 .500 12,7 .550 13,97 .510 12,95 LCI-50 .670 17,02 .700 17,78 .390 9,91 .580 14,73 .620 15,75 .590 14,99 Notes: Dimension "D" is measured across terminal blocks only. .010 MIN Coil must clear seating plane by .0,25 Mechanical HCI-68 Notes: .010 MIN Coil must clear seating plane by .0,25 Dimensions: .Inches mm Unless otherwise specified, .010 all tolerances are: .0,25 4 Power.PulseElectronics.com
