Frequently asked questions
What are the colors of a 150 Ω resistor?
On a 4-band resistor: brown, green, brown, gold. On a 5-band resistor: brown, green, black, black, brown.
What is the SMD code for 150 Ω?
151 on 3-digit resistors and 1500 on 4-digit (1%) resistors.
How much current flows through a 150 Ω resistor at 5 V?
33.3 mA, dissipating 167 mW. A 1/2 W resistor is enough.
Which resistors get mixed up with 150 Ω?
brown, green, black, gold is 15 Ω and brown, green, red, gold is 1.5 kΩ: only the third band changes, so check it carefully.
