T63 Vishay Sfernice 1/4 Multi-Turn Sealed Container Cermet Trimmers FEATURES 0.25 Watt at 85 C RoHS COMPLIANT Industrial grade Tests according to CECC 41 000 Due to their square shape and small size (6.8 x 6.8 x 5 mm), the Multi-turn operation multi-turn trimmers of the T63 series are ideally suited for PCB use, enabling high density board mounting with reduced space Low contact resistance variation 1 % typical requirement between cards. Four 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.
