1/4" Multi-Turn Fully Sealed Container Cermet Trimmer
Due to their square shape and small size (6.8 mm x 6.8 mm
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 41000 or IEC 60393-1
• Multi-turn operation
• Low contact resistance variation < 2 %
• Material categorization: for definitions of compliance
