SDR0403-120ML is a surface-mount power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supplies. It features a 12 µH inductance at 1 kHz with ±20% tolerance, a low profile of 3.2 mm maximum height, and a ferrite DR core with enameled copper wire construction. The inductor exhibits a self-resonant frequency of 30 Hz minimum, a DC resistance of 0.21 O maximum, and supports an RMS current of 1.05 A with a saturation current of 1.60 A maximum. With a temperature rise of 40°C maximum at rated current and RoHS compliance, this component is well-suited for portable communications equipment, camcorders, LCD TVs, and other compact power management applications requiring low inductance values and minimal board space.
