The LPR4012 series consists of miniature, shielded coupled inductors measuring 4 mm square and 1.1 mm high, designed for step-up, resonant, and flyback applications in DC-DC converters. Each part offers a coupling coefficient of 0.95 and 100 Vrms isolation between windings. The LPR4012-202A variant has a primary inductance of 2.0 µH with a 1:1.5 turns ratio, a maximum DC resistance of 0.240 ohms on the primary, and a saturation current of 1.70 A at 10% inductance drop. It operates from -40°C to +85°C ambient temperature with a maximum part temperature of +125°C, and complies with AEC-Q200. The termination is RoHS compliant matte tin over nickel over silver. Packaging is available as 1000 pieces per 7-inch reel.
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.
