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.
