SDR0403-680KL is a surface-mount power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supplies. The device features a 68 µH inductance at 1 kHz with ±10% tolerance, a low profile of 3.2 mm maximum height, and a ferrite DR core with enameled copper wire construction. Key electrical characteristics include a maximum DC resistance of 1.12 O, a rated RMS current of 0.46 A, a saturation current of 0.68 A, and a self-resonant frequency of 11 Hz minimum. The inductor is RoHS compliant and packaged on 2000-piece reels, making it suitable for high-volume production in portable communications equipment, camcorders, and LCD TV power supplies.
