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 (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 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 R's are measured to the tolerance specified + 0.01 . 7. Whichever is greater. 8. Load-Life test performed at nominal rated power, 0.5 W, at + 85 C.
