•
Top and bottom or top adjustment
•
Vertical and horizontal versions
•
Round or hexagonal head
MAXIMUM CONTACT RESISTANCE:
10 mΩ
MINIMUM INSULATION RESISTANCE:
10 000 MΩ
APPLICATIONS
•
For consumer and industrial equipment
CATEGORY TEMPERATURE RANGE:
PP
-40 to +70 °C
DESCRIPTION:
The vanes of the trimmer are stacked on a sturdy plastic
base. The color of the base indicates the maximum
capacitance (see Electrical Data Table). The dielectric is a
film of polypropylene (PP), polyethylene (PE), polycarbonate
(PC), polytetrafluorethylene (PTFE), or polyethyleneterephtalate
(PET) which supports the vanes in such a way that good
stability is ensured and no microphony can occur.
Flux absorption between the vanes is prevented.
Cleaning with solvents is not advised.
Versions are available with either a vertical spindle, or a
horizontal spindle (see dimensional outlines). Both versions
have top adjustment by means of a screwdriver or trimming
key and bottom adjustment by means of a key.
