SDR1307-390KL is an SMD power inductor from Bourns' SDR1307 series, featuring a 39 µH inductance at 100 kHz with ±10% tolerance and a quality factor (Q) of 28 at 2.52 MHz test frequency. The inductor has a self-resonant frequency (SRF) minimum of 9.0 MHz, a maximum DC resistance (RDC) of 75.0 mO, and supports an RMS current rating of 2.90 A with a saturation current (Isat) of 4.60 A typical. The component features a compact design with a maximum diameter of 13.0 mm (±0.5 mm) and height of 5.0 mm, making it suitable for space-constrained applications. It is RoHS compliant and experiences a temperature rise of 40°C maximum at rated Irms, with a 10% inductance drop typical at Isat. The SDR1307-390KL is ideal for input/output filtering in DC/DC converters and power supplies for portable communication equipment, camcorders, LCD TVs, and CD players.
