Bulk Metal® Foil Technology Power and Current Sensing Resistors with TCR of 2 ppm/°C, Tolerance to ± 0.01 % and power up to 10 W VFP-3, VFP-4 Vishay Foil Resistors Document Number: 63014 For any questions, contact: foil@vishaypg.com www.foilresistors.com Revision: 23-Mar-10 1 Any value available within resistance range The basic features of Vishay Bulk Metal® Foil resistors; tight resistance tolerance, fast response time, low TCR, and exceptional long-term stability, are available for power-circuit applications. Typical applications are non-inductive design, current sensing applications, de flection amplifiers, constant current power supplies, forced balance electronic scales, graphic display computers, character generation on CRTs, and electron beam controls. Our Application Engineering Department is available to advise and to make recommendations. For non-standard technical requirements and special applications, please contact us.

The resolution limit of exis ting test equipment (within the measurement capability of the equipment, or "essentially zero"). 5. Not to exceed power rating of resistor. 6. µV/°C relates to EMF due to lead temperature difference and µV/watt due to power applied to the resistor. 7. Vishay test data as compared to MIL-PRF-39009 is shown for illustration purposes, Vishay test conditions that deviate from the MIL test method are noted within parentheses. 8. Maximum ambient temperature rating is + 150 °C. 9. Maximum overload rating is 15 W (5 x rated power in free air; 1.5 x rated power on heat sink), with applied voltage not to exceed 750 V. 10. R’s are as shown plus 0.001 to allow for measurement errors at low resistance values.
