Bulk Metal® Foil Technology Ultra High Precision Trimming Potentiometers, 1/4" Square, RJ26 Style, Designed to Meet or Exceed The Requirements of MIL-PRF-39035, Char. H with a Smooth and Unidirectional Output

INTRODUCTION
Vishay Foil 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.

FEATURES
• Temperature coefficient of resistance (TCR):
   ± 10 ppm/°C. (- 55 °C to + 150 °C ref. at + 25 °C);
   through the wiper (3); ± 25 ppm/°C (see table 2 for low values)
• A smooth and unidirectional resistance with leadscrew adjustment
• Load life stability: 0.1 % typical ΔR, 1.0 % maximum ΔR under full rated power at + 85 °C for 10 000 h
• Settability: 0.05 % typical; 0.1 % maximum
• Setting stability: 0.1 % typical; 0.5 % maximum, DSS
• Power rating: 0.25 W at + 85 °C
• Resistance range: 5 Ω to 10 kΩ
• Tolerance: ± 5 %, ± 10 %
• Electrostatic discharge (ESD) up to 25 000 V
• Terminal finish: gold plated (tin/lead finish is available on request)
