Film Dielectric Trimmers
TEST VOLTAGE (DC) FOR 1 MINUTE:
600 V
FEATURES
•
High temperature type
•
Housing dimensions:
6 mm x 8 mm x 9 mm
•
For a basic grid of 2.54 mm
•
Top and bottom adjustment
•
Round or hexagonal head
•
Vertical version
MAXIMUM CONTACT RESISTANCE:
5 mΩ
MINIMUM INSULATION RESISTANCE BETWEEN
STATOR AND ROTOR:
10 000 MΩ
APPLICATIONS
•
For fine adjustment in professional applications
CATEGORY TEMPERATURE RANGE:
- 40 to + 125 °C
DESCRIPTION:
The trimmers consist of a polysulphone housing, brass rotor
and plated brass stator with PTFE film as the dielectric. The
stator plate tags are heat sealed to the housing.
The rotor contact surfaces are plated to ensure a long life
and a stable contact even under severe climatic conditions.
A coloured dot indicates the maximum capacitance.
Cleaning with solvents is not advised.
Versions are available with either a round head or hexagonal
head.
Both versions have top adjustment by means of a
screwdriver or trimming key and bottom adjustment by
means of a key.
CLIMATIC CATEGORY (IEC 60068):
40/125/21
MINIMUM STORAGE TEMPERATURE:
- 55 °C
RELATED SPECIFICATION:
IEC 60418-1 and 4
QUALITY LEVEL:
EFFECTIVE ANGLE OF ROTATION:
180° (rotation in 180° only, see “Life of Trimmer”)
Sampling and data evaluation for quality level in accordance
with
“MIL-STD-105D”
and
“IEC 60410”:
