NOTE:
(1) Version J: Inductance Value ±5 % is also available. Please add ’J’ to above part number if Inductance
Value ±5 % is required (i.e. PT12110J)
(2) Measurements are made at 25 °C using HP4277A LCZ Meter Self Resonant Frequency is for reference
only.
Full encapsulated units with Epoxy Resin are also available. Please consult factory for details.
“S” Version uses heat shrink tube for outer cover. Diameter and height are slightly higher than standard
version. (See product dimensions.)
