Resistance is measured 3/8" [9.52 mm] from the body of the resistor, or at 1.183" [30.05 mm], 1.315" [33.40 mm], 1.675" [42.545 mm] or
2.575" [65.405 mm] spacing for the LVR01, LVR03, LVR05 and LVR10 respectively
Standard resistance values are 0.01 Ω, 0.015 Ω, 0.02 Ω, 0.025 Ω, 0.03 Ω, 0.033 Ω, 0.04 Ω, 0.05 Ω, 0.051 Ω, 0.06 Ω, 0.068 Ω, 0.07 Ω, 0.08 Ω,
0.09 Ω and 0.1 Ω with 1 % tolerance. Other resistance values may be available upon request
