SDR1307-271KL is an SMD power inductor from the Bourns SDR1307 series designed for input/output filtering in DC/DC converters and power supplies. It features a 270 µH inductance at 100 kHz with ±10% tolerance, a quality factor (Q) of 15 at 0.796 MHz, and a self-resonant frequency (SRF) minimum of 3.5 MHz. The inductor has a maximum DC resistance of 410 mO, rated RMS current of 1.20 A, and typical saturation current of 1.80 A, with a compact 13 mm maximum diameter design. Operating over a temperature range of -40°C to +125°C with a maximum temperature rise of 40°C at rated current, it is constructed with a ferrite DR core and enameled copper wire with Ag/Ni/Sn terminals. This component is ideal for portable communication equipment, camcorders, LCD TVs, CD players, and car radios, offering reliable performance in space-constrained applications.
