T93 Vishay Sfernice 3/8” Square Multi-Turn Cermet Trimmers FEATURES ∑ Industrial Grade ∑ 0.5 Watt at 70°C ∑ CECC 41 100 The T93 is a small size trimmer - 3/8” x 3/8” x 3/16” - answering PC board mounting requirements. Five versions are available which differ by the position of the control screw in relation to the PC board plane and by the spacing of the terminals. Excellent operational stability is provided by the use of a cermet element. ∑ MIL-R-22097 ∑ Good stability ∑ Contact resistance variation < 1% typical ∑ Meet MIL-R-22097 specifications DIMENSIONS in millimeters T93XA Terminal Spacing on a 2.54 PCB 5 max 5±1 9.8 max 2.3 ± 0.2* a b c 2.54 2.54 9.7 max a b c ø 0.5 1.3 slot 0.6 x 0.6 0.5 ø 2.2 1.2 ± 0.2 7.9 ± 0.2 5±1 9.8 max 0.6 ± 0.2* T93XB 2.54 a b c 2.54* 2.54* 5 max a b c 9.7 max ø 0.5 1.3 0.5 ø 2.2 slot 0.6 x 0.6 1.2 ± 0.2 7.9 ± 0.2 1.2 ± 0.1 T93YA 2.3 ± 0.2* 1.3 5±1 9.8 max 1.6 ± 0.1 ø 2.2 2.54* 2.54* a b c 9.7 max a b c ø 0.5 slot 0.6 x 0.6 5 max T93YB 0.6 ± 0.2* 1.3 1.2 ± 0.1 5±1 9.8 max 2.54 1.6 ± 0.1 ø 2.2 2.54* 2.54* a b c 9.7 max ø 0.5 a b c slot 0.6 x 0.6 5 max 0.5 T93Z 4.8 ± 0.2* 5.2 max 5±1 2.54* slot 0.6 x 0.6 c b a 9.7 max 2.54* 2.54* ø 2.2 c b a ø 0.5 Base level 0.5 1.3 1.3 ± 0.1 1.2 ± 0.1 9.7 max CIRCUIT DIAGRAM * to be measured at base level Document Number: 51026 Revision: 05-Aug-04 a c (1) (3) b (2) cw For technical questions, contact: [email protected] www.vishay.com 73 T93 Vishay Sfernice 3/8” Square Multi-Turn Cermet Trimmers ELECTRICAL SPECIFICATIONS Resistive Element cermet Electrical Travel 19 turns ± 2 10W to 2.2MW Resistance Range Standard series E3 Tolerance 1 - 2.2 - 4.7 and on request 1 - 2 - 5 Standard ± 10% On Request Power Rating ± 5% Linear 0.5W at + 70°C Logarithmic not applicable Temperature Coefficient See Standard Resistance Element Table Limiting Element Voltage (Linear Law) 250V 2% Rn or 2W Contact Resistance Variation End Resistance (Typical) 1W Dielectric Strength (RMS) 1000V Insulation Resistance (500VDC) 106MW Mechanical Travel Operating Torque (max.
