12 Ohm Resistor Color Code: brown, red, black, gold

12 ohm resistor color code

The color code for 12 Ω is brown, red, black, gold on a 4-band resistor (±5%) and brown, red, black, gold, brown on a 5-band resistor (±1%).

Current through one LED in series with 12 Ω:

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

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

Same first two colors, different multiplier:

What are the colors of a 12 Ω resistor?

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

What is the SMD code for 12 Ω?

120 on 3-digit resistors and 12R0 on 4-digit (1%) resistors.

How much current flows through a 12 Ω resistor at 5 V?

417 mA, dissipating 2.08 W. A 5 W resistor is enough.

Which resistors get mixed up with 12 Ω?

brown, red, gold, gold is 1.2 Ω and brown, red, brown, gold is 120 Ω: only the third band changes, so check it carefully.
