What are Current Sense SMD Resistors?
Current Sense Resistors are similar to normal resistors but with very low resistance ratings and high power ratings. These shunt resistors of known resistor value (R) are placed in a current conducting path so that the entire current (I) which is to be measured flows through them. By measuring the voltage drop (V) across the resistor and then using simple Ohm’s Law (I=V/R), we can calculate the amount of current that flows through the circuit.
Why use a current sense resistor?
Sensing the current flow is an important requirement in many power and general electronics applications. Often, current sensing is essential to monitor and control an application; for example, a battery charger circuit requires current sensing capability to correctly charge the battery and to determine the charge current needed from the driver.
How do I choose a current sense resistor?
The first step in selecting a current sense resistor is based on understanding the application, particularly in terms of its maximum input voltage. Also, as it will be passing a heavy current (because it is connected in series with the load) its I2R losses will likely be significant even if its resistance value is small. Therefore, a knowledge of its power rating is essential.
The next step is to know the tolerance and package required for the shunt resistor. Less than 1% tolerance is a good choice. But if the application demands extra accuracy, 0.5% to 0.1% tolerance shunt resistors may be more appropriate.
After choosing the value, power rating, and tolerance, it is important to select a suitable package that is easy to solder as well as with a lower footprint for smaller PCB areas. Try to select a resistor with a very low TCR value, ideally below 100 ppm/°C.
