Notes
(1) Maximum is 1.0 % A.Q.L. standard for all specifications except
TCR. (For TCR information, see notes 2 and 3.)
(2) Maximum TCR applies to the 3 σ (sigma) limit or 99.73 % of a
production lot. (Measured end-to-end with wiper off the element.)
(3) Measurements of TCR through the wiper are influenced more by
setting stability and the percentage of the total resistance in use
(at the wiper) than by fundamental resistance change due to
temperature alone. The parameter shown in table 2 is a 2 s
distribution typifying the behavior of the device when used with
40 % or more of the total resistance in use.
(4) Derated linearly for full power at + 85 °C to zero power at
+ 150 °C. See Figure 2 on previous page.
(5) Independent of resistance value. 3 Ω maximum available on
special request.
(6) All ΔR’s are measured to the tolerance specified + 0.01 Ω.
(7) Whichever is greater.
Special Available Options:
Special marking
Burn-in and screening operations.

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)
