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.) 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. Derated linearly from full power at + 85 °C to zero power at + 150 °C. See Figure 3 in this datasheet. All ΔR’s are measured to the tolerance specified + 0.01 Ω. Whichever is greater. Load-Life test performed at nominal rated power, 0.5 W, at + 85 °C. www.foilresistors.com 4 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 VISHAY TRIMMERS ARE INSPECTED 100 % for: • Immersion • Resistance tolerance check • End resistance • Visual-mechanical • Dynamic tests for continuity, CRV By sample for: • TCR • DWV For any questions, contact: foil@vishaypg.com Document Number: 63055 Revision: 25-Mar-10 Accutrim™ 1202 Vishay Foil Resistors Circuit A is a conventional circuit employing a high value wire wound trimmer (4) linearized by two padding resistors (1 and 2) for the purpose of trimming resistor (3) to within less than 100 ppm absolute resistance. 1 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 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 CHARACTERISTICS (1) Y R=Ω K = kΩ 0 = gold plated termination (lead (Pb)-free) 1 to 999 = custom Y 5 0 5 0 5 PRODUCT CODE 0 0 R 0 TOLERANCE 5050 = 1202L 0050 = 1202LB 0051 = 1202P 6050 = 1202PB 5051 = 1202Y 7050 = 1202YB 0 0 K 0 L PACKAGING J =±5% K = ± 10 % M = ± 20 % L = foam/box pack FOR EXAMPLE: ABOVE GLOBAL ORDER Y5050 500R000 K 0 L: TYPE: 1202L VALUE: 500.0 Ω 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 B MODEL RESISTANCE VALUE TOLERANCE PACKAGING 1202L 1202LB 1202P 1202PB 1202Y 1202YB 500.0 Ω J=±5% K= ± 10 % M= ± 20 % B = bulk pack Note (1) For non-standard requests, please contact application engineering.
