About this product
A 3.3 kΩ axial power resistor rated for 2 W. Use it where a circuit dissipates more heat than a standard 1/4 W or 1 W resistor can handle, such as current limiting, voltage dividers, and bleeder or load resistors in power circuits.
Specifications
- Resistance
- 3.3 kΩ

Frequently asked questions
How do I check whether 2 W is enough for my circuit?
Calculate the dissipated power with P = V²/R or P = I²×R, then choose a rating comfortably above that value. For example, 12 V across 3.3 kΩ dissipates about 0.044 W, well within 2 W.
Can I replace a 1/4 W resistor of the same value with this one?
Yes. The resistance value is the same, and the higher power rating only adds margin. The body is larger, so check PCB space and clearance before installing.
