ADJUSTMENT
The trimmers can be adjusted with a screwdriver or
trimming key. Capacitance increase is obtained with
clockwise rotation.
MOUNTING
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.
MARKING
The trimmers are marked with the capacitance value in pF,
followed by the letter “E” (single-stator type) or the letter “D”
(differential type).
