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.

(1) Whichever is lower
(2) Heat sink chassis dimensions and requirements per
MIL-R-39009/1B:
(3) Inductance (L) due mainly to the leads
(4) The resolution limit of existing test equipment (within the
measurement capability of the equipment, or "essentially zero")
(5) µV/°C relates to EMF due to lead temperature difference
Surface mount versions of these products are available. See
datasheets for VPR220S, VPR 221S.
