SDR0604-181KL is an SMD power inductor from the SDR0604 series featuring a 180 µH inductance with ±10% tolerance, designed for input/output filtering in DC/DC converters and power supplies. The inductor utilizes a ferrite DR core with enameled copper wire and silver/nickel/tin terminals, delivering a quality factor (Q) of 20 at 0.796 MHz test frequency and a self-resonant frequency (SRF) of 6 MHz minimum. With a maximum DC resistance of 1.38 O, rated RMS current of 0.38 A, and typical saturation current of 0.50 A, this component is optimized for low-power applications. The compact package measures 5.8 mm maximum diameter with a 4.8 mm profile, making it ideal for space-constrained designs in portable communications equipment, camcorders, and LCD TV power supplies. The inductor is RoHS compliant and supplied in reels of 400 pieces.
