Additional Details:

The '301' in the part number indicates an inductance value of 300 uH (30 x 10^1 uH). The '1R5' indicates a rated current of 1.5 Amps. The PZ series inductors by Sunlord are often used in impedance matching, filtering, and decoupling applications. They feature a ceramic core and are designed for reflow soldering. The wire-wound construction provides a higher Q factor than multilayer chip inductors. Specific parameters like SRF, DCR (DC resistance) and current rating depend on the exact inductor and can be found in the datasheet. These inductors are suitable for high-frequency applications due to their stable inductance and high SRF.
