14	4.5	0.005-0.1	1.060/26.9	0.335/8.51	1.50/38.1	0.200/5.08
17	7	0.005-0.1	1.500/38.1	0.375/9.53	1.50/38.1	0.200/5.08

The Kelvin configuration enables the resistance and temperature coefficient of the terminals to be effectively eliminated. The four terminal design also results in a lower temperature coefficient of resistance and lower self-heating drift which may be experienced on two-terminal resistors. The requirement to connect to the terminals at precise test points is eliminated, allowing for tighter tolerancing on the end application.
