SDR0503-153JL is a surface-mount power inductor from Bourns' SDR0503 series designed for input/output filtering in DC/DC converters and power supply applications. The device features a high inductance of 15000 µH (15 mH) with ±5% tolerance, a compact low-profile package measuring 5.0 mm × 3.3 mm, and operates across a temperature range of -40°C to +125°C. Key electrical characteristics include a DC resistance of 168 O maximum, RMS current rating of 0.020 A, saturation current of 0.032 A, and a self-resonant frequency of 1.0 MHz. The inductor utilizes a ferrite DR core with enameled copper wire and silver/nickel/tin plated terminals, offering RoHS compliance and moisture sensitivity level 1. This component is ideal for portable communications equipment, camcorders, LCD TVs, and other compact power management systems requiring high inductance values in minimal board space.
