| T6 Vishay Sfernice 1/4" Multiturn Fully Sealed Container Cermet Trimmers FEATURES * * * * * * * * * * * * Military and professional grade 0.25 Watt at 85C CECC 41 101-005 (A, B, C, D) MIL-R-22097 (RJ26) GAM T1 Space saving Excellent stability Low contact resistance variation 1% typical Fully sealed Excellent setting accuracy Wide range of ohmic values Tape and reel available Due to their square shape and small size (6.8 x 6.8 x 5mm), the multiturn trimmers of the T6 series are ideally suited for PCB use, enabling high density board mounting with reduced space 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.
