SDE0604A-680K is an SMD power inductor from the SDE0604A series featuring a nominal inductance of 68 µH with ±10% tolerance, designed for high-saturation-current applications. The inductor exhibits a typical DC resistance of 0.343 O (maximum 0.46 O) and operates at a self-resonant frequency of 11 MHz, with rated RMS current of 1.0 A and saturation current of 0.74 A. Housed in a compact 5.8 × 5.2 × 4.5 mm package with ferrite core and enameled copper windings, it operates reliably across -40°C to +125°C with a typical temperature rise of 40°C at rated current. The device is AEC-Q200 compliant, RoHS compliant, and halogen-free, making it suitable for automotive, industrial power conversion, and consumer electronics applications requiring stable inductance and low losses in space-constrained designs.
