| T63 Vishay Sfernice 1/4" Multiturn Sealed Container Cermet Trimmers FEATURES * 0.25 Watt at 85C * Industrial grade * CECC 41 100 * MIL-R-22097 Due to their square shape and small size (6.8 x 6.8 x 5 mm), the multiturn trimmers of the T63 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. * Multiturn operation * A low contact resistance variation * Tight tolerancing * Low end contact resistance DIMENSIONS in millimeters T63XA O 0.45 2.54 2.54 screwdriver slot 0.5 x 0.5 2.3 0.2 6.8 0.2 4 min. 5 max. a b c TERMINAL SPACING ON A 2,54 PCB a b c 6.8 0.2 0.25 0.7 O 1.8 5.7 0.1 1 0.1 T63XB 1.2 0,3 2.54 6.8 0.2 4 min. 5 max. a b c a b c 2.54 2.54 screwdriver slot 0.5 x 0.5 6.8 0.2 0.25 0,7 O 1.8 5.7 0.1 1 0.1 T63YA O 0.45 2.54 2.54 2.3 0.2 7,8 max. 6.8 0.2 4 min. 5 max. 1 0.1 1.3 0.1 a b c O 1.8 6.8 0.2 a b c 0.25 T63YB 1.2 0.3 2.54 2.54 2.54 6.8 0.2 4 min. 5 max. 1 0.1 1.3 0.1 a b c O 1.8 6.8 0.2 a b c 0.25 T63ZA 6.8 0.2 O 1.8 6.8 0.2 c b a 3.7 6.8 0.2 2.54 2.54 1.3 0.1 c b a 1 0.1 c b a 2.54 2.54 T63ZB 6.8 0.2 O 1.8 2.54 3.7 5 max. 4 min. c b a CIRCUIT DIAGRAM a (1) b (2) cw c (3) www.vishay.com 58 For technical questions, contact sfer@vishay.com Document Number: 51024 Revision 01-Mar-02 T63 1/4" Multiturn Sealed Container Cermet Trimmers ELECTRICAL SPECIFICATIONS Resistive Element Electrical Travel Resistance Range Standard Series and on Request Series E3 Tolerance Power Rating Temperature Coefficient Limiting Element Voltage (Linear Law) Contact Resistance Variation End Resistance (Typical) Dielectric Strength (RMS) Standard On request Linear cermet 13 turns 2 10 to 2M 1 - 2 - 5.
