Vitrohm Shunt Resistors
Quick Overview
Vitrohm Shunt Resistors
Vitrohm Shunt Resistors offer a rated power range of 2.2W to 10W, resistance values up to 0.05Ω, and AEC-Q200 qualification. These resistors feature a power current sensor, excellent overload and heat dissipation capabilities, low inductance, welded construction, and superior stability in various environmental conditions. Available in open frame, ceramic case, and molded versions, Vitrohm Shunt Resistors are ideal for pulse applications, switching equipment, instrumentation, and power amplifiers.

Vitrohm Shunt Resistors Overview
A shunt resistor diverts current by providing a low-resistance path, making it useful for current measurement in circuits. By directing most of the current through the shunt, the voltage across it can be measured and used to calculate the total current.
Applications of Shunt Resistors
Vitrohm’s Current Sense Shunt Resistors are widely used in automotive and industrial markets to detect current in high-power systems. In the automotive industry, the shift towards computerized and electro-mechanical systems, driven by the demand for increased safety, efficiency, and electric vehicles, has led to a greater need for compact shunt resistors to support the growing number of motors and ECUs.
