Resistance decreases with increasing the operating frequency of the curve
Temperature coefficient of resistance within the specified ambient temperature range, the temperature changes by 1 ℃, the average relative Electric transformer with ppm / ℃ representation. Several parameters in addition to the above, there are non-linear, voltage coefficient (every change of the applied voltage, volt resistance relative rate of change), current noise, high-frequency mcb circuit breaker (resistance in vivo in the distributed capacitance and inductance, so resistance decreases with power transformers the operating frequency of the curve, the long-term stability of the resistors in the course of long-term use or storage of the impact resistance by environmental conditions irreversible process of change and other technical indicators.
