This release in:

MALVERN, Pa. — Jan. 16, 2009 — Vishay Intertechnology Inc. (NYSE: VSH) today announced two new compact panel potentiometers with high dielectric strength of 5,000 VRMS, cermet and conductive plastic elements, and a wide variety of modules and terminal styles.

With their 12.5-mm size, the new P11P and P11D offer designers a compact alternative to other low-cost panel potentiometers. The P11P's cermet element provides better stability than carbon elements, while the conductive plastic element of the P11D offers a reduced electrical noise for audio applications. Both devices feature a 5,000-VRMS dielectric strength for greater reliability, robustness, and corrosion protection, and offer insulated plastic shafts and bushing, with value-added options in accordance with drawings supplied by customers.

The versatile panel potentiometers offer a wide range of configurations for control panel applications in welding machines, air conditioning units, tooling machines, medical systems, and X-ray equipment. The devices feature up to seven modules, two shaft lengths, and 29 terminal styles. Offered in shaft and panel-sealed versions, the P11P and P11D provide up to 21 indent positions along with rotary switch options.

The new Vishay Sfernice devices offer a typical operating torque from 0.3 oz. to 1.4 oz. per inch, and an end stop torque of 6.8 lb. per inch. The potentiometers provide a resistance range from 20 Ω to 10 MΩ with a typical contact resistance variation down to 1 %, and TCR down to 150 ppm/C. Tested in accordance to CECC41 000, the devices offer an operating temperature range of -40 C to +100 C to ensure reliable operation even in extreme environments.

Device Specification Table:

Part number P11D P11P
Element Conductive plastic Cermet
Resistance range 1 kΩ to 1 MΩ 20 Ω to 10MΩ
Contact resistance variation (typ.) 1 % 2 % or 3 Ω
Temperature coefficient (typ.) 500 ppm/C 150 ppm/C
Life cycles 50,000 50,000

Samples and production quantities of the new panel potentiometers are available now, with lead times of eight to 10 weeks for larger orders.
