FEATURES

• Ideal for all types of current sensing applications

including switching and linear power supplies,

instruments and power amplifiers

• Proprietary processing technique produces

extremely low resistance values

• Excellent load life stability

• Low temperature coefficient

• Low inductance

• Cooler operation for high power to size ratio

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)

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
