() 0 Ω at ± 5 % available on special order. () Maximum TC applies to the σ (sigma) limit or 99.7 % of a production lot. (Measured end-to-end with wiper off the element.) (4) Measurements of TC 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 is a 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 power at + 50 C. See Figure in this datasheet. (6) All Δ s are measured to the tolerance specified Ω. (7) Whichever is greater.

5 Vishay Foil esistors Circuit A is a conventional circuit employing a high value wire wound trimmer (4) linearized by two padding resistors ( and ) for the purpose of trimming resistor () to within less than 00 ppm absolute resistance. Circuit B uses only a low value infinite resolution Vishay trimming potentiometer (5) to accomplish the same results. Saving in cost and board space is achieved. A low value wire wound trimmer cannot be used because of poor resolution. 4 5 Circuit A Circuit B TABLE 6 - LOBAL PAT NUMBE INFOMATION NEW LOBAL PAT NUMBE: K0L (preferred part number format) DENOTES PECISION VALUE CHAACTEISTICS () = Ω K = kω 0 = gold plated termination (lead (Pb)-free) to 999 = custom K 0 L PODUCT CODE TOLEANCE PACKAIN 5050 = 0L 0050 = 0LB 005 = 0P 6050 = 0PB 505 = = 0B () For non-standard requests, please contact application engineering.
