NOTE:
Pad layout guidelines per MIL-STD-275E
(printed wiring for electronic equipment).
Tolerances: xx ± 0.01" [± 0.25 mm]; xxx ± 0.005"
[± 0.12 mm]
The underside of these components contains
metal and thus should not come in contact with
active circuit traces.
* 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.
