Notes:
1. Maximum TCR applies to the 3 s (sigma) limit or 99.73 % of a
production lot. (Measured end-to-end with wiper off the element.)
2. 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.
3. Derated linearly for full power at + 85 °C to zero (0) W at
+ 150 °C. See figure 2.
4. All
ΔR’s
are measured to the tolerance specified + 0.01
Ω.
5. Whichever is greater.
Special available options:
