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. www.vishay.com 76 Document Number 34067 Revision 27-Apr-99 Model LPE-6855 Vishay Dale DIMENSIONAL CONFIGURATIONS [Numbers in brackets indicate millimeters] Pad Layout 0.045 [1.14] Pad Dimensions Typical, 8 places 5 0.079 [2.01] 0.045 [1.14] 0.593 [15.06] 0.638 [16.21] Reference Only Typical 3 places 8 Clip Opening Opposite Pin 1 1 4 .555 [14.10] Max. .690 [17.53] Max. .079 [2.01] Typ.
