Frequently asked questions
What are the colors of a 3 kΩ resistor?
On a 4-band resistor: orange, black, red, gold. On a 5-band resistor: orange, black, black, brown, brown.
What is the SMD code for 3 kΩ?
302 on 3-digit resistors and 3001 on 4-digit (1%) resistors.
How much current flows through a 3 kΩ resistor at 5 V?
1.67 mA, dissipating 8.33 mW. A 1/8 W resistor is enough.
Which resistors get mixed up with 3 kΩ?
orange, black, brown, gold is 300 Ω and orange, black, orange, gold is 30 kΩ: only the third band changes, so check it carefully.
