Maximum TCR applies to the 3  (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 3 is a 2  distribution typifying the behavior of the device when used with 40 % or more of the total resistance in use. Derated linearly from full power at + 85 °C to zero power at + 150 °C. See Figure 3 in this datasheet. All R’s are measured to the tolerance specified + 0.01 . Whichever is greater.

Saving in cost and board space is achieved. A low value wire wound trimmer cannot be used because of poor resolution. 4 3 3 5 2 Circuit A Circuit B TABLE 6 - GLOBAL PART NUMBER INFORMATION NEW GLOBAL PART NUMBER: Y5050500R000K0L (preferred part number format) DENOTES PRECISION VALUE Y R =  K = k Y 5 0 5 0 5 PRODUCT CODE 5050 = 1202L(2) 0050 = 1202LB(2) 0051 = 1202P(1) 6050 = 1202PB(1) 5051 = 1202Y(1) 7050 = 1202YB(1) 0 0 CHARACTERISTICS (3) 0 = gold plated pins (lead (Pb)-free) 0 = silver plated copper wire terminations (lead (Pb)-free); styles L & LB 1 to 999 = custom R 0 0 0 K 0 TOLERANCE PACKAGING J = ± 5 % K = ± 10 % M = ± 20 % L = foam/box pack L FOR EXAMPLE: ABOVE GLOBAL ORDER Y5050 500R000 K 0 L: TYPE: 1202L VALUE: 500.0  ABSOLUTE TOLERANCE: ± 10.0 % TERMINATION: gold plated (lead (Pb)-free) PACKAGING: foam/box pack HISTORICAL PART NUMBER: 1202L 500R00 K B (will continue to be used) 1202L 500R00 K MODEL RESISTANCE VALUE TOLERANCE PACKAGING 500.0  J = ± 5 % K= ± 10 % M= ± 20 % B = bulk pack 1202L(2) 1202LB(2) 1202P(1) 1202PB(1) 1202Y(1) 1202YB(1) B Notes (1) (2) (3) Pin leads are gold plated nickel which are solderable or weldable (lead (Pb)-free).
