•
For a basic grid of 2.54 mm
•
Top adjustment
•
Vertical version
e3
MAXIMUM CONTACT RESISTANCE:
5 mΩ
MINIMUM INSULATION RESISTANCE BETWEEN
STATOR AND ROTOR:
10 000 MΩ
APPLICATIONS
•
For fine adjustment in professional applications
DESCRIPTION:
The trimmers consist of a glass reinforced polysulphone
frame with a polysulphone dust cover, brass rotor and stator
with PTFE or polycarbonate film as the dielectric. The stator
plates are stacked on pins and separated by rings, so that it
is possible to produce a single stator or a differential type.
The rotor contact surfaces are plated to ensure a long life
and a stable contact even under severe climatic conditions.
CATEGORY TEMPERATURE RANGE:
- 40 to + 125 °C
CLIMATIC CATEGORY (IEC 60068):
40/125/21
QUALITY LEVEL:
Sampling and data evaluation for quality level in accordance
with
“MIL-STD-105D”
and
“IEC 60410”:
MINIMUM STORAGE TEMPERATURE:
- 55 °C
< 0.15 % major defects
< 0.65 % minor defects
Each capacitor is tested for minimum C
max
and is also
subjected to the full test voltage.

Trimmers 2281 809 07... series
Dimensions in millimeters
ADJUSTMENT:
The trimmers can be adjusted with a screwdriver or trimming
key. Capacitance increase is obtained with clockwise
rotation
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)
.
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
.
PACKAGING:
Blister packs of 70 units each. For smallest packaging
quantity (SPQ) see Electrical Data Table.
