摘要： A compound resistor is formed of a resistive material making up a predominant portion of the resistance and having a small negative TCR coupled with an adjustment material having an extremely low resistance and a very high positive temperature coefficient of resistance. After the manufacturing process, a portion of the adjustment material is removed to adjust the composite TCR of the compound resistor substantially to zero without significantly affecting the resistance.
