About this product
A 1 W carbon film through-hole resistor with a 100 Ω value and 5% tolerance. It suits general-purpose circuits such as current limiting, pull-up or pull-down and biasing, as long as the dissipated power stays within its 1 W rating.

Frequently asked questions
What are the colour bands for 100 Ω 5%?
Brown, black, brown, gold: brown = 1, black = 0, brown = ×10, gold = ±5%, giving 10 × 10 = 100 Ω.
Is 1 W enough for my circuit?
Calculate the dissipated power as P = V²/R or P = I²R. If it stays comfortably below 1 W, the resistor is suitable; higher loads need a higher wattage.
