ADJUSTMENT
MARKING
The trimmers can be adjusted with a screwdriver or
trimming key. Capacitance increase is obtained with
clockwise rotation.
The trimmers are marked with the capacitance value in pF,
followed by the letter “E” (single-stator type) or the letter “D”
(differential type).
MOUNTING
PACKAGING
The trimmer can be mounted on printed-circuit boards with
a grid of 2.54 mm and a minimum hole diameter of 1.25 mm.
Blister packs of 70 units each. For smallest packaging
quantity (SPQ) see “Electrical Data” table.
