Notes
1. Preferred Termination style for current 1-1/4 inch rectilinear
trimmers (staggered PC pins present a sturdier mounting
arrangement for shock, vibration, and impact situations).
2. 10 W at ± 5 % available on special order.
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.)
4. 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 3 is a 2
σ
distribution typifying the behavior of the device when used with
40 % or more of the total resistance in use.
5. Derated linearly from full power at + 85 °C to zero (0) W at
+ 150 °C. See Figure 3 in this data sheet.
6. All
ΔR’s
are measured to the tolerance specified + 0.01
Ω.
7. Whichever is greater.
8. Load-Life test performed at nominal rated power, 0.5 W, at
+ 85 °C.
Special Available Options:
Special marking
Special lengths for lead wires (L, LB Style)
Hooked leads
Alternate bushing and PC combinations
Power conditioning and screening operations
