About this product
A 5 W ceramic cement power resistor rated at 470 Ω. Power resistors of this type are used where a part must dissipate more heat than a standard 1/4 W resistor, such as current limiting, load testing or dropping voltage in higher-power circuits. Mount it with clearance for heat dissipation.

Frequently asked questions
Can it handle 5 W continuously?
It is rated for 5 W, but it needs airflow or clearance to dissipate heat. Derate it in hot environments or in enclosed spaces.
What is the maximum current through it?
At 470 Ω and 5 W, the current that reaches the rated dissipation is about 103 mA (I = √(P/R) = √(5/470) ≈ 0.103 A).
