Foil Resistors Accutrim™1240 Series Trimmers

Vishay Precision Group/Foil Resistors Accutrim™1240 Series (RJ26 Style) Trimming Potentiometers have the Bulk Metal® Foil resistive element which possesses a unique inherent temperature and load-life stability. In addition, the ultra high-precision, 1/4" square 1240 series trimmers feature an advanced, virtually backlash-free adjustment mechanism for easy and accurate set-up that remains stable. Features of 1240 series trimming potentiometers include resistance range of 5Ω to 10kΩ, power rating of 0.25W at +85ºC, electrostatic discharge (ESD) up to 25,000V, and smooth, unidirectional resistance with leadscrew adjustment. The 1240 series trimmers were designed to meet the requirements of MIL-PRF-39035, Char H.
