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 Terminal Spacing on a 2.54 PCB DIMENSIONS in millimeters T93XA 2.54 2.54 9.8 max 2.3 ± 0.2* a b c 1.3 0.5 7.9 ± 0.2 5±1 5 max 9.7 max ø 0.5 a b c slot 0.6 x 0.6 ø 2.2 1.2 ± 0.2 T93XB 2.54 0.6 ± 0.2* 9.8 max 5±1 5 max 2.54* 2.54* a b c 1.3 0.5 7.9 ± 0.2 9.7 max ø 0.5 a b c slot 0.6 x 0.6 ø 2.2 1.2 ± 0.2 T93YA 2.54* 2.54* 1.2 ± 0.1 2.3 ± 0.2* 1.3 ø 2.2 9.8 max 5±1 1.6 ± 0.1 a b c 9.7 max ø 0.5 5 max a b c slot 0.6 x 0.6 T93YB 0.6 ± 0.2* 2.54 ø 2.2 2.54* 2.54* 1.3 9.8 max 5±1 1.2 ± 0.1 1.6 ± 0.1 a b c 9.7 max ø 0.5 5 max a b c slot 0.6 x 0.6 0.5 T93Z 4.8 ± 0.2* 5.2 max 2.54* slot 0.6 x 0.6 2.54* 2.54* ø 2.2 1.3 9.7 max 0.5 1.3 ± 0.1 1.2 ± 0.1 c b a 5±1 c b a 9.7 max ø 0.5 Base level CIRCUIT DIAGRAM a (1) c (3) b (2) cw * to be measured at base level Document Number: 51026 Revision: 05-Aug-04 For technical questions, contact: sfer@vishay.com www.vishay.com 73 T93 Vishay Sfernice 3/8” Square Multi-Turn Cermet Trimmers ELECTRICAL SPECIFICATIONS Resistive Element Electrical Travel Resistance Range Standard series E3 Tolerance Power Rating Temperature Coefficient Limiting Element Voltage (Linear Law) Contact Resistance Variation End Resistance (Typical) Dielectric Strength (RMS) Insulation Resistance (500VDC) Standard On Request Linear Logarithmic cermet 19 turns ± 2 10W to 2.2MW 1 - 2.2 - 4.7 and on request 1 - 2 - 5 ± 10% ± 5% 0.5W at + 70°C not applicable See Standard Resistance Element Table 250V 2% Rn or 2W 1W 1000V 106MW MECHANICAL SPECIFICATIONS Mechanical Travel Operating Torque (max.
