Vishay has unveiled two new series of high-precision Accutrim trimming potentiometers. The 3/4-inch rectilinear devices offer low end-to-end TCR of ±5 ppm/°C (1285G) and ±15 ppm/°C (1280G) from –55°C to +125°C, + 25°C reference, and ±25 ppm/°C through the wiper, load life stability of 0,1% under full rated power at +25°C for 2000 hours, and less than 0,05% typical settability.
The 1280G and 1285G trimmers feature a bulk metal foil resistive element that possesses a unique inherent temperature and load life stability. Their advanced, virtually backlash-free (less than 0,05%) adjustment mechanism makes them easy to set quickly and accurately, and maintains that setting through temperature cycling and vibration, as well as thermal and mechanical shock. The devices offer a multifingered, noble metal wiper engaging a planar surface of etched foil for low TCR end-to-end and through the wiper.
The devices feature a 0,1% typical setting stability, a wide resistance range from 10 Ω to 20 kΩ, and resistance tolerances of ±5% (1285G) and ±10% (1280G). They offer a 0,75 W power rating at +25°C and 26 ±2 turn adjustments. For increased reliability, they can withstand electrostatic discharges up to 25 kV.
