The SPT38L-294MLD is a surface mount toroidal power inductor from the SPT series, designed for high current applications with a saturation current rating of 0.90 A at 30% inductance drop and a root mean square current rating of 1.0 A causing a 20°C temperature rise from 25°C ambient. It has an inductance of 290 µH with a DC resistance of 657 mΩ and a self-resonant frequency of 2.87 MHz. The component uses a powered iron core, features RoHS-compliant tin-silver over copper terminations, and complies with MSL level 1 for moisture sensitivity. Its physical dimensions are 0.56 in × 0.56 in × 0.37 in (14.22 mm × 14.35 mm × 9.50 mm). The operating ambient temperature range is −40°C to +85°C, with a maximum part temperature limit of +85°C. The toroidal construction minimizes electromagnetic emissions.
The Coilcraft SPT Series of high current surface mount (SM) toroidal power inductors have very high current ratings - up to 12.2 Amps. The toroidal construction provides magnetic shielding that eliminates EMI and allows for closer component placement.
