About this product
A 0.56 ohm, 0.5 W (1/2 watt) through-hole resistor. Low-value resistors like this are used in current sensing, load and test circuits, and in power-limiting applications. Check the power rating against the expected current before use.

Frequently asked questions
What is the maximum current this resistor can handle?
Using P = I²R, the current at the 0.5 W limit is about 0.94 A (sqrt(0.5 / 0.56)). Stay below this, and with margin, to avoid overheating.
How can I confirm the value before using it?
Measure it with a multimeter in resistance mode, with the resistor removed from the circuit or with its leads isolated, since very low resistances can be affected by lead and contact resistance.
