Frequently asked questions
What are the colors of a 100 kΩ resistor?
On a 4-band resistor: brown, black, yellow, gold. On a 5-band resistor: brown, black, black, orange, brown.
What is the SMD code for 100 kΩ?
104 on 3-digit resistors and 1003 on 4-digit (1%) resistors.
How much current flows through a 100 kΩ resistor at 5 V?
50 µA, dissipating 250 µW. A 1/8 W resistor is enough.
Which resistors get mixed up with 100 kΩ?
brown, black, orange, gold is 10 kΩ and brown, black, green, gold is 1 MΩ: only the third band changes, so check it carefully.
