Technical Specifications
The PA3019NL is a power inductor. Key specifications include inductance value, saturation current, DC resistance (DCR), and self-resonant frequency (SRF). The inductance value determines the energy storage capability of the inductor. The saturation current indicates the maximum current the inductor can handle before its inductance drops significantly. Low DCR minimizes power loss in the inductor, and a high SRF ensures the inductor performs well at the desired operating frequency. The specific inductance value for the PA3019NL would be available in the datasheet, typically in the microhenry (µH) range.
