SDR0503-331KL is a surface-mount power inductor from Bourns' SDR0503 series designed for input/output filtering in DC/DC converters and power supplies. It features an inductance of 330 µH at 1 kHz with ±10% tolerance, a ferrite DR core with enameled copper wire, and a compact profile of only 3.3 mm maximum height. The inductor has a maximum DC resistance of 3.30 O, rated RMS current of 0.210 A, and saturation current of 0.280 A, with a self-resonant frequency of 5.0 MHz minimum. It is RoHS compliant and suitable for portable communications equipment, camcorders, and LCD TV power supplies where space constraints and reliable filtering are essential.
