NOTES:

1. Maximum is 1.0% A.Q.L. standard for all specifications except TCR. (For TCR information see notes 2 and 3). “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 stated or better.

2. Maximum TCR applies to the 3

(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 is a 2

distribution typifying the behavior of the device when used with 40% or more of the total resistance in use.

4. Derated linearly from full power @ + 85°C to zero (0) watts @ + 150°C. See Figure 2, next page.

5. Independent of resistance value 3 ohms maximum available on special request.
