Introduction
0805 Size 0.05Ω (50m Ohm) 0.75W Current Sensing Resistor For 5G Base Station Applications
In modern electronics, precise current measurement is essential for efficiency, control, and safety. The 0805 0.05Ω (50m Ohm) 0.75W 1% STE00805MW75R050F current sensing resistor is engineered for high-performance and reliability in demanding applications.
Introduction to Current Sensing Resistors
Unlike standard resistors, current sensing resistors are specifically designed to convert flowing current into a measurable voltage drop based on Ohm's Law (V = I * R). Placed in series with the load, the voltage developed across them is measured by monitoring circuitry. The accuracy of this system depends heavily on the performance of the sensing resistor.
