| P8S Vishay Sfernice Fully Sealed Container Cermet Trimmers FEATURES * Industrial grade * High quality cermet resistive track: * 1 Watt at 70 C, P8ST * 0.5 Watt at 70 C, P8SX - P8SY * CECC 41100 * Wide resistance range (10 to 2.2 M) Three versions are available: The P8S series trimmers are extremely well adapted for all industrial applications as their maximum resistance contact variation is within 3 % of Rn and as they are fully sealed. For more stringent requirements the P8P series is recommended. - P8SX, with shaft parallel to the PC board plane - P8SY, with shaft perpendicular to the PC board plane - P8ST, for front panel mounting RoHS COMPLIANT } Outlets PCB mounting DIMENSIONS in millimeters P8SX P8SY P8ST o 8.5 2.54 2.54 O 11 0.5 slot 0.6 wide x 0.7 deep o 8.5 0.5 8 max 8.6 a b c 2.54 5 min 0.5 x 0.4 8.9 4.7 3.5 min slot 0.6 wide x 0.7 deep c 7.62 2.54 2.54 b 2.54 2.54 1 Thread M7 x 0.75 shim washers 3.2 0.2 2.54 a 3.4 0.2 7.8 1 4.5 1 -0 O 8.6 - 0.1 Panel thickness 1 0.4 2 3 Ground 2 0.5 to 2.5 0.5 min 3 2.5 to 4 max * Tolerance unless otherwise specified: 0.5 Consult Vishay SFERNICE for panel sealed type CIRCUIT DIAGRAM a (1) b (2) cw c (3) Document Number: 51020 Revision: 26-Oct-06 For technical questions, contact: sfer@vishay.com See also: Application notes www.vishay.com 51 P8S Vishay Sfernice Fully Sealed Container 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 (500 VDC) Standard On Request P8SX - P8SY P8ST cermet 270 15 10 to 2.2 M 1 - 2.2 - 4.7 and on request 1 - 2 - 5 10 % 5% 0.5 W at 70 C 1 W at 70 C See Standard Resistance Element Table 250 V 3 % Rn or 3 1 1000 V 1 G MECHANICAL SPECIFICATIONS Mechanical Travel Operating Torque (max.
