FAQs
-
What is the tolerance in a resistor?
Tolerance indicates the accuracy of the resistor’s stated resistance. For example, ±5% means the actual resistance may vary by 5% above or below the stated value.
-
What does the 6th band (PPM) indicate?
It represents the temperature coefficient, showing how the resistance changes with temperature. It’s mostly used in precision resistors.
