SDR0503-222JL 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 an inductance of 2200 µH (±5% tolerance) with a ferrite DR core and enameled copper wire construction, delivering a maximum DC resistance of 22.00 O and a self-resonant frequency of 2.0 MHz. The inductor operates at a rated RMS current of 0.053 A with a saturation current of 0.070 A, and maintains a temperature rise of 40°C maximum at rated current. With a compact profile of only 3.3 mm height and dimensions of 5.0 × 4.8 mm, this component is ideal for space-constrained portable communications equipment, camcorders, and LCD TV power supplies where high inductance and low profile are essential.
