3 / 5 page Document Number: 63014 For any questions, contact: foil@vishay.com www.vishay.com Revision: 29-Aug-07 3 VFP-3, VFP-4 Bulk Metal® Foil Technology Power and Current Sensing Resistors with TCR of 2 ppm/°C, Tolerance to ± 0.01 % and power up to 10 Watts Vishay Foil Resistors Notes 1. Whichever is lower. 2. Heat sink chassis dimensions and requirements per MIL-PRF-39009: 3. Inductance (L) due mainly to the leads. 4. The resolution limit of existing 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. ΔR’s are as shown plus 0.001 Ω to allow for measurement errors at low resistance values.
