SDR0503-220ML is an SMD power inductor from Bourns' SDR0503 series designed for input/output filtering in DC/DC converters and power supply applications. The device features a 22 µH inductance at 1 kHz with ±20% tolerance, a low profile of 3.3 mm, and a self-resonant frequency (SRF) minimum of 22.0 MHz. It delivers an RMS current rating of 0.900 A with a saturation current of 1.060 A and a maximum DC resistance of 0.28 O, making it suitable for portable communication equipment, camcorders, LCD TVs, and car radios. The inductor is RoHS compliant and operates reliably across a temperature range of -40°C to +125°C, with ferrite core construction and enameled copper windings for optimal performance in compact power management designs.
