SD53-3R3-R is a low-profile shielded inductor from the SD53 series designed for high-power applications requiring compact board space utilization. It features a rated inductance of 3.30 µH with an octagonal shape and 5.2 mm × 5.2 mm × 3.0 mm surface-mount package, incorporating a shielded ferrite drum core that reduces electromagnetic interference. The inductor operates at an RMS current of 2.26 A and saturation current of 2.60 A, with a typical DC resistance of 0.029 O at 20°C and maximum of 0.034 O. Operating temperature range is -40°C to +125°C, with a maximum solder reflow temperature of 260°C for 10 seconds. This component is ideal for high-power LED drivers, buck/boost converter applications, DSL modems, digital cameras, cellular phones, and battery power supply circuits where space efficiency and EMI suppression are critical.
