SDR0403-560KL is a surface-mount power inductor from the Bourns SDR0403 series designed for input/output filtering in DC/DC converters and power supply applications. The device features an inductance of 56 µH at 1 kHz with a tolerance of ±10%, a low profile of 3.2 mm maximum height, and a self-resonant frequency of 12 MHz. It has a DC resistance of 0.94 O, a saturation current of 0.74 A, and operates reliably across a temperature range of -40°C to +125°C. The inductor is constructed with a ferrite DR core and enameled copper wire with silver/nickel/tin terminals, making it ideal for portable communication equipment, camcorders, LCD TVs, and automotive radio applications where compact size and low inductance values are essential.
