Notes
(1)
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.
(2)
LVR01: Standard resistance values are 0.01 , 0.015 , 0.02 , 0.025 , 0.03 , 0.033 , 0.04 , 0.05 , 0.051 , 0.06 , 0.068 ,
