The SRR4028-680Y is a shielded SMD power inductor from the Bourns SRR4028 series. It features an inductance of 68 µH with a ±30% tolerance, a maximum DC resistance (DCR) of 400 mΩ, and a typical self-resonant frequency (SRF) of 11 MHz. This component is rated for a saturation current (Isat) of 0.360 A and an RMS current (Irms) of 0.63 A. With its compact size and shielded construction, it is ideal for use in the input/output stages of DC/DC converters and power supplies for portable electronics like camcorders and LCD TVs.
