注释

All readings taken on Agilent/HP 4342-A Q meter.
L min is achieved at maximum extension of the core toward PC board. Complete tuning range is reached within the boundaries of the coil form.
All specifications are recommended at standard Q meter frequency as a simple way to ensure the quality of our parts. L and Q readings will vary with frequency change.
