About this product
A 0.33 ohm power resistor rated at 2 watts. Low-value resistors like this are used for current sensing, load limiting and current measurement in power circuits. Check the power dissipation before use, because high current through it will heat it.

Frequently asked questions
What is the price of 0.33 Ohm 2W Power Resistor (0.33Ω, 2W) in Egypt?
0.33 Ohm 2W Power Resistor (0.33Ω, 2W) currently costs 2 EGP in Egypt.
Where can I buy 0.33 Ohm 2W Power Resistor (0.33Ω, 2W) in Egypt?
0.33 Ohm 2W Power Resistor (0.33Ω, 2W) is available from Microohm. Compare the offers above to find the best price.
What is the maximum current this resistor can handle?
From P = I²R, the current at full 2W rating is about I = √(2 / 0.33), which is roughly 2.46A. Stay well below this value, since continuous operation at full rating leads to high temperatures.
Can I use it to measure current with an Arduino?
Yes. Place it in series with the load and measure the voltage across it, since V = I × R. At 1A it produces about 0.33V, which is small, so use a differential amplifier or op-amp stage before the ADC input.
