3 / 5 page VPR221SZ (Z-Foil) Vishay Foil Resistors Ultra High Precision Z-Foil Surface Mount Power Resistor in TO-220 Configuration with TCR of ± 0.05 ppm/°C, PCR of 4 ppm/W and Load Life Stability of ± 0.005 % (50 ppm) www.vishay.com For any questions, contact: foil@vishay.com Document Number: 63127 3 Revision: 11-Jun-07 Notes 1. Whichever is lower. 2. Heat sink chassis dimensions are requirements per MIL-R-39009/1B: 3. Inductance (L) mainly due to the leads. 4. The resolution limit of existing test requirement (within the measurement capability of the equipment, “essentially zero”). 5. µV/°C relates to EMF due to lead temperature difference. Note 1.
