Additional Details:

The RLF7030T-2R2M5R4-B features an inductance of 2.2µH. The 'M' signifies an inductance tolerance of ±20%. The datasheet provides information about saturation current (Isat) and rated current (Irms). These values are crucial for selecting the inductor for a specific application, as they indicate the current levels at which the inductance starts to drop significantly and the maximum current the inductor can handle continuously without overheating. The operating temperature range typically extends from -40°C to +125°C. The core material used is typically a ferrite compound, optimized for power applications. The self-resonant frequency (SRF) is a relevant parameter, especially for high-frequency applications; it represents the frequency at which the inductor transitions from inductive to capacitive behavior.
