FAQs

  1. 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.

  2. 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.
