*DC current that will create a maximum temperature rise of 30C when applied at + 25C 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.
NOTE: Pad layout guidelines per MIL-STD275E (printed wiring for electronic equipment). Tolerances: xx 0.01" [ 0.25mm]. xxx 0.005" [ 0.12mm].
