Additional Details:

The SPM10054T-1R5M-D has an inductance value of 1.5 μH. The 'M' in the part number typically indicates an inductance tolerance (e.g., ±20%). It has a saturation current rating that indicates the current at which the inductance drops by a specified percentage. It is important to select an inductor with a saturation current rating that is higher than the maximum current in the application to avoid saturation. The operating temperature range is generally between -40°C and +125°C. Consult the manufacturer's datasheet for detailed specifications, including inductance tolerance, saturation current, DC resistance, and self-resonant frequency.
