SRU3017-3R3Y is a shielded SMD power inductor from Bourns' SRU3017 series designed for input/output filtering in DC/DC converters and power supply applications. The inductor features a 3.3 µH inductance at 100 kHz with ±30% tolerance, a maximum RMS current rating of 1.45 A, and a saturation current of 0.80 A typical. It incorporates a ferrite DR and RI core with enameled copper wire (Class F) and silver/nickel/tin terminals, housed in a compact 3.5 mm × 3.3 mm × 1.8 mm package. With a self-resonant frequency of 80 MHz and DC resistance of 55 mO, this inductor is well-suited for portable communication equipment, camcorders, and LCD TV power supplies where space and performance are critical.
