FEATURES

• Housing diameter 7.5 mm

• For a basic grid of 2.54 mm (0.1") or 2.50 mm

• Top and bottom or top adjustment

• Vertical and horizontal versions

• Round head

APPLICATIONS

• For consumer and industrial equipment

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.

QUALITY LEVEL:

Sampling and data evaluation for quality level in accordance

with “MIL-STD-105D” and “IEC 60410”:

Each capacitor is tested for minimum C

subjected to the full test voltage.

1.4/5.5 to 3/50 pF

RATED VOLTAGE (DC):

250 V

LIFE OF TRIMMER:

Maximum 10 cycles: rotation in 180° only (the electrical and

mechanical performance is not guaranteed if rotated beyond

10 cycles)
