1 / 7 page Document Number: 63024 For any questions, contact: foil@vishay.com www.vishay.com Revision: 25-Oct-07 1 Bulk Metal® Foil Technology Discrete Chips with TCR of 2 ppm/°C and Tolerance to 0.005 % for use in Hybrid Circuits V5X5P, V15X5P, V15X10P Vishay Foil Resistors The typical pattern and trimming illustrations show that the V5X5P resistor has 16 trimming points, the V15X5P has 20 and the V15X10P has 21. These trimming points are arranged around the chip periphery and are clearly indicated. Trimming to the desired resistance value and tolerance is accomplished by cutting the trim points, thereby producing specific incremental changes in the chip’s resistance value relative to the original prevalue; up to + 20 % for the V5X5P, + 30 % for the V15X5P, and + 50 % for the V15X10P (not all trim points need be used; the ΔR necessary to adjust the pre-value to the desired final value dictates which trim points neet to be used). Monitoring of circuit output while “actively” trimming readily permits adjustment of the chip to ± 0.005 %. Actual trimming charts are supplied on request for all images. FEATURES • Temperature coefficient of resistance (TCR): Absolute: ± 2.0 ppm/°C typical (- 55 °C to + 125 °C, + 25 °C ref.) Tracking: to 0.5 ppm/°C1, 2) • Resistance tolerance: Absolute to ± 0.01 % (user trimmable to ± 0.005 %) Match: to 0.01 % • Power rating: 50 to 150 mW at + 70 °C • Load life stability: ± 0.05 % maximum at + 70 °C, 2000 h at rated power • Resistance range: 5 Ω to 80 kΩ (see table 2) • Short time overload: ≤ 0.02 % • Electrostatic discharge (ESD) above 25 000 V • Non inductive, non capacitive design • Rise time: 1 ns without ringing • Current noise: - 40 dB • Non inductive: < 0.08 µH • Non hot spot design Vishay precision chip resistors offer an order of magnitude of improvement over other chip resistors in hybrid applications. With a maximum Temperature Coefficient of Resistance (TCR) of ± 5 ppm/°C, selected TCR tracking to 0.5 ppm/°C and factory supplied resistance tolerances to ± 0.01 %, they provide the user with accuracy and stability not available in other chip resistor products. If desired they can be user trimmed to any value within ± 0.005 %. Vishay precision chip resistors are designed to meet or exceed the requirements of MIL-PRF-55342 characteristic E. These discrete chips are available either factory trimmed to exact resistance values (option T) or ready for user trimming (option U).
