SMD Inductors Large-Current Power Inductors TPI Overview Applications The KEMET TPI ferrite core inductors are designed for Hard-switching topology for DC/DC conversion a very low core loss. Its flat wire, one turn through the Soft-switching topology for AC resonant conversion construction design, enables high efficiency at large Point of loads (POL) currents. The core material is ideal for high switching Servers and storage frequency applications. Supercomputers Various decentralized power supplies The TPI series offers two solutions. One set of parts are DC optimized inductors for hard SW topology, 12 V power distribution. The other set comprises AC optimized inductors for soft SW topology, 48 V power distribution. These AC optimized inductors were developed for STC (Switched Tank Convertor) technology. Benefits One turn coil ferrite Operating temperature up to +125C High switching frequency Low core loss Low DCR High current Low self-heating AC optimized inductor reduce close to 50% the total loss compared to conventional inductor due to optimized structure and material designed for STC technology Part Number System TPI 128080 L 180 N Series Size Code Inductor Inductance Code nH Version TPI 077050 xxx = xxx nH N = Standard 078060 111065 118082 128080 Built Into Tomorrow KEMET Electronics Corporation KEMET Tower One East Broward Boulevard L9010 TPI 7/6/2021 1 Fort Lauderdale, FL 33301 USA 954-766-2800 www.kemet.comSMD Inductors Large-Current Power Inductors TPI Performance Characteristics Item Performance Characteristics Operating Temperature 40C to +125C (including self-temperature rise) Rated Inductance Range 47 230 nH at 100 kHz, 1 mA Inductance Tolerance 10% (except 20% for TPI077050L105N) Rated DC Resistance 0.29 0.32 m DC Resistance Tolerance 5% (except 9.5% for TPI077050L105N and 10.0% for TPI078060L***N) Rated Current 36 53 A Table 1 Ratings & Part Number Reference DC Optimized TPI Inductors Rated Current (A) Inductance DC Inductance 2 Part Number (nH) at 100 Resistance Isat (Ref.) 1 Tolerance Irms (Ref.) kHz, 1 mA (m) 25C 85C 125C TPI077050L105N 105 20% 0.32 9.5% 36 60 51 44 TPI118082L150N 150 10% 0.29 5.0% 50 93 79 67 TPI118082L180N 180 10% 0.29 5.0% 50 79 67 57 TPI111065L210N 210 10% 0.29 5.0% 50 54 46 38 TPI128080L180N 180 10% 0.29 5.0% 50 78 68 54 TPI128080L210N 210 10% 0.29 5.0% 50 70 60 52 TPI128080L230N 230 10% 0.29 5.0% 50 64 56 50 1 T = 40 K rise at rated current 2 Inductance drop 20% at rated current All electrical characteristics data is referenced to 25C.
