Vishay Sfernice
1/4" Multi-Turn Fully Sealed Container
Cermet Trimmers
Due to their square shape and small size (6.8 x 6.8 x 5 mm), the
multi-turn trimmers of the T63 series are ideally suited for PCB
use, enabling high density board mounting with reduced space
requirement between cards.
Six versions are available differing by the top or side position of
the adjustment screw and by PC pins configuration.
The use of cermet for the resistive track ensures an excellent
stability of nominal specifications throughout life.
FEATURES
•0.25 W at 70 °C
•Industrial grade
•Tests according to CECC 41 000
