Maximum is 1.0 % A.Q.L. standard for all specifications except

100 % for:

• Immersion

• Resistance tolerance check

• End resistance

• Visual-mechanical

TCR. (For TCR information, see notes 2 and 3.)

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.)

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.

Derated linearly for full power at + 85 °C to zero power at

+ 150 °C. See Figure 2 on previous page.

Independent of resistance value. 3 Ω maximum available on

special request.

• Dynamic tests for continuity, CRV

• TCR

• DWV
