11 P8S www.vishay.com Vishay Sfernice 8.5 mm Diameter Single-Turn Fully Sealed Container Cermet Trimmer FEATURES Industrial grade High quality cermet resistive track: - 1 W at 70 C, P8ST - 0.5 W at 70 C, P8SX and P8SY Test according to CECC 41000 or IEC 60393-1 Wide resistance range (10 to 2.2 M ) Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 The P8S series trimmers are 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.
