Additional Details

The SQC321618T-2R2K-N inductor typically has a specified self-resonant frequency (SRF), which is the frequency at which the inductor's impedance reaches its maximum value. Above the SRF, the inductor behaves capacitively. The datasheet from Chilisin provides detailed specifications, including inductance tolerance, DC resistance (DCR), saturation current (Isat), rated current, and operating temperature range. Proper selection of the inductor requires careful consideration of these parameters to ensure optimal performance in the target application.
