Frequently asked questions
What are the colors of a 220 Ω resistor?
On a 4-band resistor: red, red, brown, gold. On a 5-band resistor: red, red, black, black, brown.
What is the SMD code for 220 Ω?
221 on 3-digit resistors and 2200 on 4-digit (1%) resistors.
How much current flows through a 220 Ω resistor at 5 V?
22.7 mA, dissipating 114 mW. A 1/4 W resistor is enough.
Which resistors get mixed up with 220 Ω?
red, red, black, gold is 22 Ω and red, red, red, gold is 2.2 kΩ: only the third band changes, so check it carefully.
