VPR220S, VPR221S
Vishay Foil Resistors
Bulk Metal® Foil Technology Precision Foil Power Surface Mount
Resistors in TO-220 Configuration with TCR of ± 2 ppm/°C,
Tolerance of to ± 0.01 % and Power Rating to 8 W
FEATURES
Any value at any tolerance within resistance range
Models VPR220S AND VPR221S, made from Vishay Bulk
Metal® foil, offer low TCR, high stability, tight tolerance and
fast response time in a small, molded resistor. Model
VPR220S is a 2 lead device. Model VPR221S is a 4 lead
Kelvin connected device. The 4 leaded version is highly
recommended for precision applications requiring ohmic
values of 100R or less.
