The Coilcraft LPR4012-202LMRC is a low-profile, shielded coupled inductor designed for flyback and step-up applications, measuring 4 mm square and 1.1 mm high. It features a 1:10 turns ratio, 2.0 µH primary inductance, 11.62 Ω secondary DCR, and a saturation current of 1.70 A at 10% inductance drop. The component provides 100 Vrms isolation between windings and operates from -40°C to +85°C ambient with a maximum part temperature of +125°C. It has a coupling coefficient of 0.95, a self-resonant frequency of 7.43 MHz, and is rated for a 20°C temperature rise at 1.10 A RMS current. Termination is RoHS compliant matte tin over nickel over silver. The part is packaged in 7" machine-ready reels with EIA-481 embossed plastic tape, has moisture sensitivity level 1, and meets AEC-Q200 standards at +85°C.
Coilcraft LPR4012 Series low-profile 1:N coupled power inductors are ideal for a variety of voltage step-up and step-down applications, including low voltage step-up in energy harvesting designs. They offer excellent coupling coefficient (K > 0.95) and 100 Vrms, one-minute isolation (hipot) between windings.
