Frequently asked questions
What are the colors of a 1 MΩ resistor?
On a 4-band resistor: brown, black, green, gold. On a 5-band resistor: brown, black, black, yellow, brown.
What is the SMD code for 1 MΩ?
105 on 3-digit resistors and 1004 on 4-digit (1%) resistors.
How much current flows through a 1 MΩ resistor at 5 V?
5 µA, dissipating 25 µW. A 1/8 W resistor is enough.
Which resistors get mixed up with 1 MΩ?
brown, black, yellow, gold is 100 kΩ and brown, black, blue, gold is 10 MΩ: only the third band changes, so check it carefully.
