OHMITE LVK Series Current Sense Resistors

OHMITE LVK Series Current Sense Resistors monitor voltage drop across a precisely calibrated resistance that helps measure current flow in a circuit. The LVK resistors feature a Kelvin configuration that eliminates the resistance and temperature coefficient of the terminals for a more accurate current measurement. These LVK resistors offer an excellent Temperature Coefficient of Resistance (TCR) even for shallow resistance values. The LVK current sense resistors operate over a temperature range from -40°C to +125°C. These resistors have various applications, including automotive, consumer goods, medical, military, and telecom.
