The LPD4012 series consists of shielded, surface-mount coupled inductors designed for flyback, SEPIC, and multi-output buck applications. Each component measures 4.0 mm × 4.0 mm × 1.1 mm and is packaged in tape and reel formats. The parts are AEC-Q200 Grade 1 qualified for operation from -40°C to +125°C ambient temperature, with a maximum part temperature of +165°C. The LPD4012-682MR variant has an inductance of 6.8 µH ±20% per winding, a DC resistance of 0.530 Ω max per winding, and a saturation current of 1.20 A at 30% inductance drop. The coupling coefficient is 0.99, and the self-resonant frequency is 31 MHz. Termination is RoHS-compliant matte tin over nickel over silver. The inductors support a winding-to-winding isolation of 100 Vrms for one minute and meet MSL 1 moisture sensitivity. The parts are halogen-free, lead-free, and suitable for reflow soldering up to three cycles at 260°C.
Coilcraft LPD4012 Series surface-mount 1:1 coupled power inductors are ideal for Flyback, SEPIC, Cuk, Zeta and other applications. Their compact, low-profile design and magnetic shielding make them ideal for high-density circuits.
