P8P
Vishay Sfernice
Fully Sealed Container Cermet Trimmers
FEATURES
* Military and professional grade * 1 Watt at 70 C, P8PT * 0.5 Watt at 70 C, P8PX - P8PY * CECC 41 101-002 (A, B) Models P8PX and P8PY feature a TO-5 transistor type, rugged metal case housing. The cermet track is printed to an alumina substrate allowing high dissipation and ensuring reliable performance under extreme environmental conditions. Models P8PX and P8PY are qualified PC 39 and PC 19 respectively according to CECC 41 101-002 mod. A and B. * GAM T1 * Fully sealed P8P series are available in three mounting configurations: - P8PX, side adjust with pins Outlets PCB - P8PY, top adjust with pins mounting - P8PT, panel mount with solder lugs
