*DC current that will create a maximum temperature rise of 30°C when applied at + 25°C ambient. **DC current that will typically reduce the initial inductance by
20%.
UNGAPPED MODELS:
Highest possible inductance with the lowest DCR and highest Q capability. Beneficial in filter, impedance matching and line coupling
devices.
GAPPED MODELS:
Capable of handling large amounts of DC current, tighter inductance tolerance with better temperature stability than ungapped models.
Beneficial in DC to DC converters or other circuits carrying DC currents or requiring inductance stability over a temperature range.
