SDR0503-101KL is a surface-mount power inductor from Bourns' SDR0503 series, designed for input/output filtering in DC/DC converters and power supply applications. It features a 100 µH inductance at 1 kHz with ±10% tolerance, a low profile of 3.3 mm maximum height, and a ferrite DR core with enameled copper wire construction. The inductor delivers 0.400 A RMS rated current with a maximum DC resistance of 1.60 O and a saturation current of 0.480 A, providing reliable performance in compact power management circuits. With a self-resonant frequency of 9.0 MHz and RoHS compliance, this component is ideal for portable communications equipment, camcorders, LCD TVs, and other space-constrained power supply designs requiring high inductance in a minimal footprint.
