Models VPR220 AND VPR221, made from Vishay Bulk Metal
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.
