SDR0403-1R8ML 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 with an inductance of 1.8 µH at 1 kHz, a tolerance of ±20%, and a ferrite DR core with enameled copper wire construction. The device exhibits a maximum DC resistance of 0.042 O, a self-resonant frequency minimum of 90 Hz, and supports an RMS current of 2.91 A with a saturation current of 4.4 A. With a temperature rise of 40 °C maximum at rated current and RoHS compliance, this inductor is well-suited for portable communications equipment, camcorders, LCD TVs, and other compact power supply designs requiring low inductance values and minimal board space.
