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), polycarbonate (PC) or
polytetrafluorethylene (PTFE), 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.
Both versions have top adjustment by means of a
screwdriver or trimming key and bottom adjustment by
means of a key.

MINIMUM STORAGE TEMPERATURE:

- 55 °C

RELATED SPECIFICATION:

IEC 60418-1 and 4

EFFECTIVE ANGLE OF ROTATION:

180° (rotation in 180° only, see “Life of Trimmer”)

QUALITY LEVEL:

Sampling and data evaluation for quality level in accordance
with “MIL-STD-105D” and “IEC 60410” :

< 0.15 % major defects

< 0.65 % minor defects

Each capacitor is tested for minimum C
subjected to the full test voltage.
