Frequently Asked Questions
How can a 0.39 ohm resistor support current measurement?
A 0.39 ohm element produces a voltage proportional to load current, allowing an amplifier or controller to calculate current from the measured drop.
How accurate is the initial resistance value?
The resistor specifies 1% tolerance around 0.39 ohm, while temperature coefficient, self-heating, solder joints, and PCB trace resistance add system error.
What should sourcing compare for another low-value resistor?
Match 0.39 ohm resistance, 1% tolerance, footprint, power rating, pulse capability, temperature coefficient, terminal construction, finish, and qualification level.
