SDR1307-330KL is an SMD power inductor from Bourns' SDR1307 series, featuring a 33 µH inductance at 100 kHz with ±10% tolerance. The inductor has a compact design with a maximum diameter of 13.0 mm and dimensions of 13.0 ± 0.5 mm (diameter) by 7.0 ± 0.3 mm (height), making it suitable for space-constrained applications. Key electrical characteristics include a quality factor (Q) of 35 at 2.52 MHz test frequency, a self-resonant frequency (SRF) minimum of 10.0 MHz, a maximum DC resistance (RDC) of 65.0 mO, an RMS current rating of 3.10 A, and a saturation current (Isat) of 5.00 A typical with a 10% voltage drop. The device is RoHS compliant and rated for a maximum temperature rise of 40°C at rated current, making it ideal for input/output filtering in DC/DC converters and power supplies for portable communication equipment, camcorders, LCD TVs, and CD players.
