Module 3. Electrical fundamentals

The 5th coloured band on a resistor represents the

  • reliability or temperature coefficient.
  • tolerance.
  • multiplier.

Explanation

On a five-band military-style resistor the additional band beyond the value, multiplier and tolerance bands denotes the reliability (failure-rate) factor or temperature coefficient rather than repeating tolerance or multiplier. The multiplier and tolerance are carried by earlier bands.

MridulDev asking:
