注释

DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
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 readings taken on Agilent/HP 4342-A Q Meter.
All specifications are at standard “Q” meter frequencies. L and Q readings change with frequency.
Shielded parts have a sleeve insert to protect the winding.

端子:

Pins: Tin-lead over tin over copper over iron
Shield can tabs: Tin-silver over nickel over brass
