What is a temperature compensation resistor?
Temperature compensation is a common problem among coils, or solenoids. These metals exhibit a positive temperature coefficient with rising temperature. Since the NTC typically has temperature coefficient range of –0.29% to –0.51%, a fixed parallel resistor is used to bring the temperature coefficient down to a usable limit.
