FEATURES
• High temperature type
• Housing dimensions:
• For a basic grid of 2.54 mm
• Top and bottom adjustment
• Round head
APPLICATIONS
• For fine adjustment in professional applications
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.
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.
C
0.5/2 to 2/18 pF
RATED VOLTAGE (DC):
300 V
LIFE OF TRIMMER:
Maximum 10 cycles: rotation in 180° only (the electrical and
mechanical performance is not guaranteed if rotated beyond
10 cycles)
