22 Ohm Resistor Color Code: red, red, black, gold

22 ohm resistor color code

The color code for 22 Ω is red, red, black, gold on a 4-band resistor (±5%) and red, red, black, gold, brown on a 5-band resistor (±1%).

Current through one LED in series with 22 Ω:

Above 20 mA: too much for a common 5 mm LED.

22 Ω is a standard value in the E6, E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 22 Ω resistor?

On a 4-band resistor: red, red, black, gold. On a 5-band resistor: red, red, black, gold, brown.

What is the SMD code for 22 Ω?

220 on 3-digit resistors and 22R0 on 4-digit (1%) resistors.

How much current flows through a 22 Ω resistor at 5 V?

227 mA, dissipating 1.14 W. A 3 W resistor is enough.

Which resistors get mixed up with 22 Ω?

red, red, gold, gold is 2.2 Ω and red, red, brown, gold is 220 Ω: only the third band changes, so check it carefully.
