SDR0403-1R4ML is an SMD power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supply applications. It features a 1.4 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 delivers a rated RMS current of 3.30 A with a maximum saturation current of 5.10 A, a DC resistance of 0.038 O maximum, and a self-resonant frequency minimum of 110 Hz. With a temperature rise of 40°C maximum at rated current and RoHS compliance, this component is ideal for portable communications equipment, camcorders, LCD TVs, and other compact power supply designs requiring low inductance values and minimal board space.
