T93 Vishay Sfernice 3/8" Square Multi-Turn Cermet Trimmers FEATURES * Industrial Grade * 0.5 W at 70 C RoHS COMPLIANT * Tests according to CECC 41 000 * Contact resistance variation < 1 % typical 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. * Lead (Pb)-free and RoHS compliant Terminal Spacing on a 2.54 PCB DIMENSIONS in millimeters 9.8 max 51 5 max 2.3 0.2* T93XA a b c 2.54 2.54 1.3 slot 0.6 x 0.6 0.5 o 2.2 1.2 0.2 7.9 0.2 9.8 max 0.6 0.2* T93XB 51 2.54 5 max a b c 2.54* 2.54* a b c 9.7 max o 0.5 1.3 0.5 o 2.2 slot 0.6 x 0.6 1.2 0.2 7.9 0.2 1.3 2.3 0.2* T93YA a b c 9.7 max o 0.5 9.8 max 1.2 0.1 51 1.6 0.1 o 2.2 a b c 2.54* 2.54* 9.7 max o 0.5 a b c slot 0.6 x 0.6 0.5 0.6 0.2* 1.3 T93YB 9.8 max 5 max 1.2 0.1 51 2.54 o 2.2 2.54* 2.54* a b c 1.6 0.1 9.7 max o 0.5 slot 0.6 x 0.6 a b c 5 max 0.5 4.8 0.2* T93Z 5.2 max 51 2.54* slot 0.6 x 0.6 c b a 9.7 max 2.54* 2.54* o 0.5 c b a Base level o 2.2 0.5 1.3 1.3 0.1 1.2 0.1 9.7 max CIRCUIT DIAGRAM a c (1) (3) b (2) cw Tolerance unless otherwise specified 0.5 * to be measured at base level Document Number: 51026 Revision: 26-Jun-07 For technical questions, contact: sfer@vishay.com www.vishay.com 73 T93 3/8" Square Multi-Turn Cermet Trimmers Vishay Sfernice ELECTRICAL SPECIFICATIONS Resistive Element cermet Electrical Travel 21 turns 2 Resistance Range 10 to 2.2 M Standard series E3 1 - 2.2 - 4.7 and on request 1 - 2 - 5 Tolerance Standard 10 % On Request Power Rating 5% Linear 0.5 W at + 70 C Logarithmic not applicable Temperature Coefficient See Standard Resistance Element Table Limiting Element Voltage (Linear Law) 250 V 2 % Rn or 2 Contact Resistance Variation End Resistance (Typical) 1 Dielectric Strength (RMS) 1000 V Insulation Resistance (500 VDC) 106 M Mechanical Travel Operating Torque (max.
