Frequently asked questions
What is the SMD code for a 330 resistor?
331 on 3-digit (5%) SMD resistors and 3300 on 4-digit (1%) ones.
How can I tell which end to start reading from?
Start from the end opposite the gold (5%) or brown (1%) tolerance band, which is often set slightly apart.
Is 330 a standard resistor value?
Yes, it belongs to the E12 series, so it is available in every common tolerance.
