SDR0403-331KL is a surface-mount power inductor from Bourns' SDR0403 series designed for input/output filtering in DC/DC converters and power supplies. It features a 330 µH inductance at 1 kHz with ±10% tolerance, a low profile height of 3.2 mm maximum, and a ferrite DR core with enameled copper wire construction. The inductor exhibits a maximum DC resistance of 6.00 O, a rated RMS current of 0.17 A, and a saturation current of 0.25 A, with a self-resonant frequency of 4 Hz minimum. This compact design is ideal for portable communications equipment, camcorders, and LCD TV power supplies where space constraints and low inductance values are critical requirements.
