- Typical minimum requirements to be specified for a Surface Mount Inductor are:
- No load inductance in uH.
- Full load inductance in uH.
- DC Current in Amperes.
- AC Current in Amperes peak to peak.
- Operating frequency is needed for core calculations and wire sizing.
- Core material is selected for the known operating frequency or frequencies.
- Other Surface Mount Inductor design considerations are space limitations of the bobbin or toroid mounting technique.
- Size limitations are limited by available surface mount bobbins and headers.
Surface Mount Inductor designs vary widely in terms of power rating, inductance, voltage level, operating frequency, size, impedance, bandwidth (frequency response), packaging, winding capacitance, and other parameters.
