Notes  
1. 5 Ω, 10 Ω, and 20 Ω resistance values available on special order.  
2. 5 % resistance tolerance available on special order.  
3. Maximum is 1.0 % A.Q.L. standard for all specifications except TCR. (For TCR information, see notes 4 and 5.) “Typical” is a designers  
reference which represents that 85 % of the lots supplied, over a long period of time, will be at least the figure shown or better.  
4. 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.)  
5. 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.  
6. Derated linearly for full power at + 85 °C to zero (0) W at + 150 °C. See figure 2 on previous page.  
7. Whichever is greater.  
8. All ΔR’s are measured to the tolerance specified + 0.01 Ω.
