The SRU1048-331Y is a shielded surface-mount power inductor from Bourns' SRU1048 series designed for input/output filtering in DC/DC converters and power supply applications. It features an inductance of 330 µH at 100 kHz with a quality factor (Q) of ±30, a DC resistance of 3.0 mO, and a self-resonant frequency of 0.796 MHz. The inductor is rated for a maximum RMS current of 490 A with a saturation current of 0.65 A, and operates reliably over a temperature range of -40°C to +125°C. With a compact unit height of 4.8 mm and RoHS compliance, it is well-suited for portable communication equipment, camcorders, LCD TVs, and other space-constrained power management applications requiring stable inductance and low core losses.
