SDR0403-1R0ML is a surface-mount power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supply applications. It features a low profile of 3.2 mm maximum height, ferrite DR core with enameled copper wire, and silver/nickel/tin plated terminals for reliable soldering. The inductor delivers 1.0 µH inductance at 1 kHz with ±20% tolerance, a self-resonant frequency minimum of 150 Hz, and a maximum DC resistance of 0.033 O, supporting an RMS current rating of 3.80 A and saturation current of 5.50 A. Temperature rise is limited to 40°C maximum at rated current, and the device is RoHS compliant. This compact inductor is ideal for portable communications equipment, camcorders, LCD TVs, and other space-constrained power management circuits requiring low inductance values and minimal profile.
