SDR0805-121KL is a surface-mount power inductor from Bourns' SDR0805 series, featuring a 120 µH inductance with ±10% tolerance. The inductor utilizes a ferrite DR core with enameled copper wire and silver/nickel/tin terminals, housed in a compact 7.8 mm maximum diameter package. Key electrical characteristics include a DC resistance of 0.48 O maximum, a rated RMS current of 0.66 A, a saturation current of 1.00 A maximum, and a self-resonant frequency of 6 MHz minimum, with a quality factor of 12 at 0.796 MHz test frequency. The device is rated for a maximum temperature rise of 40°C at rated current and is RoHS compliant. This inductor is well-suited for input/output filtering in DC/DC converters and power supplies for portable communications equipment, camcorders, LCD TVs, and CD players.
