SDR0503-102KL 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 an inductance of 1000 µH (±10% tolerance) with a maximum DC resistance of 11.50 O and a self-resonant frequency of 3.0 MHz minimum. It is rated for an RMS current of 0.110 A and a saturation current of 0.135 A, with a low profile of 3.3 mm maximum height and ferrite core construction. The inductor operates reliably across a temperature range of -40°C to +125°C and is RoHS compliant, making it suitable for portable communication equipment, camcorders, LCD TVs, and automotive radio applications where compact size and high inductance values are required.
