VISHAY MODELS VPR220 AND VPR221  
Pre c is ion Foil Pow e r Re s is tors in TO 220 Configura tion  
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 de-  
vice. 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.
