Additional Details:

The 1111SQ-30NGEC features a ceramic core and is constructed with materials that minimize losses at high frequencies. The inductance value is 30 nH with a specified tolerance. The self-resonant frequency (SRF) is an important parameter, indicating the frequency at which the inductor's behavior becomes capacitive. The DC resistance (DCR) is typically very low, minimizing power dissipation. Specific data sheets should be consulted for detailed electrical characteristics, including Q factor vs. frequency curves, SRF, and DCR.
