Frequently asked questions
What are the colors of a 270 Ω resistor?
On a 4-band resistor: red, violet, brown, gold. On a 5-band resistor: red, violet, black, black, brown.
What is the SMD code for 270 Ω?
271 on 3-digit resistors and 2700 on 4-digit (1%) resistors.
How much current flows through a 270 Ω resistor at 5 V?
18.5 mA, dissipating 92.6 mW. A 1/4 W resistor is enough.
Which resistors get mixed up with 270 Ω?
red, violet, black, gold is 27 Ω and red, violet, red, gold is 2.7 kΩ: only the third band changes, so check it carefully.
