Frequently asked questions
What are the colors of a 1.2 kΩ resistor?
On a 4-band resistor: brown, red, red, gold. On a 5-band resistor: brown, red, black, brown, brown.
What is the SMD code for 1.2 kΩ?
122 on 3-digit resistors and 1201 on 4-digit (1%) resistors.
How much current flows through a 1.2 kΩ resistor at 5 V?
4.17 mA, dissipating 20.8 mW. A 1/8 W resistor is enough.
Which resistors get mixed up with 1.2 kΩ?
brown, red, brown, gold is 120 Ω and brown, red, orange, gold is 12 kΩ: only the third band changes, so check it carefully.
