LVT Series
Low Value Current Sense
The Ohmite LVT series is s metal alloy strip resistor providing
good TCR ratings. Low value stability is important when using
a current sense resistor. The LVT offers TCR ratings down to
50ppm with tolerances down to 1%. The LVT series provides
a resistance range from 2m to 20m ohms. TCR stability with
tight tolerances and wide resistance range makes the LVT series
suited for most current sense applications.
