SDR0403-180ML is an SMD power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supply applications. The inductor features an inductance of 18 µH at 1 kHz with ±20% tolerance, a ferrite DR core with enameled copper wire, and a compact low-profile design of only 3.2 mm maximum height. Key electrical characteristics include a DC resistance of 0.34 O maximum, RMS current rating of 0.84 A, saturation current of 1.30 A maximum, and a self-resonant frequency minimum of 23 Hz. The device is housed in a surface-mount package with Ag/Ni/Sn terminals, rated for a maximum temperature rise of 40°C at rated current, and is RoHS compliant. This inductor is ideal for portable communications equipment, camcorders, LCD TVs, and other compact power supply designs requiring low inductance values and minimal board space.
