Notes:
1. All readings taken on Agilent/HP
4342-A Q Meter.
2. 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.
3. All specifications are at standard “Q”
meter frequencies. L and Q readings
change with frequency.
4. Shielded parts have a sleeve insert
to protect the winding.
5. Operating temperature range -40°C
to +85°C.
6. Electrical specifications at 25°C.
