SDR1806-471KL is a surface-mount power inductor from Bourns' SDR1806 series designed for input/output filtering in DC/DC converters and power supply applications. The device features a 470 µH inductance at 100 kHz with ±10% tolerance, a low profile of 6.6 mm, and a ferrite DR core with enamelled copper wire construction. Key electrical characteristics include a maximum DC resistance of 820 mO, a rated RMS current of 0.80 A, a saturation current of 1.50 A typical, and a self-resonant frequency of 3.0 MHz. The inductor operates over a temperature range of -40°C to +125°C with a maximum temperature rise of 40°C at rated current, and is RoHS compliant. This component is ideal for portable communications equipment, camcorders, LCD TVs, and other compact power supply designs where space efficiency and reliable filtering are essential.
