VPR220, VPR221 Vishay Foil Resistors Bulk Metal® Foil Technology Precision Foil Power Resistors in TO-220 Configuration with TCR of ± 2 ppm/°C, Tolerance of to ± 0.01 % and Power Rating to 8 W Any value at any tolerance within resistance range Models VPR220 AND VPR221, made from Vishay Bulk Metal® Foil, offer low TCR, high stability, tight tolerance and fast response time in a small, molded resistor. Model VPR220 is a 2 lead device. Model VPR221 is a 4 lead Kelvin connected device. The 4 leaded version is highly recommended for precision applications requiring ohmic values of 100R or less. TABLE 1 - VPR220 RESISTANCE RANGE (Ω) (1) TIGHTEST TOLERANCE 50 to 10K 25 to < 50 10 to < 25 5 to < 10 ± 0.01 % ± 0.02 % ± 0.05 % ± 0.
