Ceramic rods are coated with a metal film and plated steel caps are force fitted. A helical cut is used to adjust the film to its final value. Termination wires are welded to the caps and the resistor is protected with a specially formulated epoxy coating. Terminations Material Solder-coated copper wire. Strength The terminations meet the requirements of IEC 68.2.21 Solderability The terminations meet the requirements of IEC 115-1, Clause 4.17.3.2 Ultra Precision Metal Film Resistors CAR series © Welwyn Components Limited Bedlington, Northumberland NE22 7AA, UK Telephone: +44 (0) 1670 822181 · Facsimile: +44 (0) 1670 829465 · Email: info@welwyn-tt.com · Website: www.welwyn-tt.com 179 Welwyn Components Values 10 ≤ 250k Values > 250k Actual Performance Actual Performance Maximum Typical Maximum Typical Load at rated power : 1000 hrs at 70°C (or 85°C) ∆R % 0.05 0.02 0.25 0.05 Dry heat : 1000 hrs at 155°C ∆R % 0.15 0.08 1 0.2 Shelf life : 12 months at room temperature ∆R % 0.01 0.003 0.04 0.02 C°551 ta oreZC°551 ta oreZ)C°58 ro( C°07 ta rewop detar morf gnitareD Short term overload ∆R % 0.01 0.001 0.08 0.01 Climatic ∆R % 0.05 0.02 0.2 0.05 65/551/5565/551/55yrogetac citamilC Long term damp heat ∆R % 0.05 0.02 0.2 0.05 Temperature rapid change ∆R % 0.04 0.02 0.25 0.05 Resistance to solder heat ∆R % 0.02 0.003 0.05 0.005 Vibration and bump ∆R % 0.02 0.002 0.06 0.02 1.0130.02.0V/Vµ)ycneuqerf fo edaced a ni( esioN 50.0<2.050.0<3.0V/mppecnatsiser fo tneiciffeoc egatloV Marking Type reference, TCR code, resistance value and tolerance code.

Performance Data Application Notes Resistors can be supplied matched for tolerance and TCR down to ±0.005% and ±1ppm/°C, respectively, either as separate resistors or pre-assembled and encapsulated within a plastic box. The individual resistors within a set or module can be manufactured with a tolerance of ±0.01% and a TCR of ±5ppm/°C. f1 f2 Body location f1 – f2 ≤ 1.4 mm Make Possible 12.14 General Note TT Electronics reserves the right to make changes in product specification without notice or liability.
