NOTES:
(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.)
