Frequently Asked Questions
What is the tolerance of these resistors?
These carbon film resistors have a ±5% tolerance, meaning each 220 Ω resistor can vary by up to 11 Ω from its nominal value.
Can I use them for LED current limiting?
Yes. At 20 mA through a 220 Ω resistor, the dissipation is I²R ≈ 0.088 W, well below the 0.25 W rating, making them ideal for protecting LEDs.
How do I read the color code on these resistors?
They use a Red-Red-Brown-Gold banding: Red (2), Red (2), Brown (×10 multiplier), Gold (±5% tolerance) indicates 22×10 = 220 Ω ±5%.
