T93YB253KT20 Vishay

T93 Vishay Sfernice 3/8 Square Multi-Turn Cermet Trimmers FEATURES Industrial Grade RoHS 0.5 Watt at 70 C COMPLIANT Tests according to CECC 41 000 The T93 is a small size trimmer - 3/8 x 3/8 x 3/16 - answering PC board mounting requirements. Contact resistance variation < 1 % typical Five versions are available which differ by the position of the control screw in relation to the PC board plane and by the spacing Lead (Pb)-free and RoHS compliant of the terminals. Excellent operational stability is provided by the use of a cermet element.
