The Precision trimmers have the Bulk Metal® Foil resistive element which possesses a unique inherent temperature and load life stability. Plus, their advanced virtually back lash-free adjustment mechanism makes them easy to set quickly and accurately and keeps the setting exactly on target.
Temperature coefficient of resistance (TCR): ± 10 ppm/°C maximum (- 55 °C to + 150 °C ref. at + 25 °C); through the wiper (4); ± 25 ppm/°C
A smooth and unidirectional resistance with leadscrew adjustment
Load life stability: 0.1 % typical ΔR, 0.5 % maximum ΔR under full rated power at + 85 °C for 2000 h
