label:
1, the nominal resistance: resistor above the marked resistance.
2,
the allowable error: the nominal resistance and the actual value of the
difference between the nominal resistance as a percentage of resistance
called resistance deviation, which means that the accuracy of the
resistor, the allowable error and accuracy grade as follows: ± 0.5% - 0.05, ± 1% -0.1 (or 00), ± 2% -0.2 (or 0), ± 5% -Ⅰ, ± 10% -Ⅱ, ± 20% -Ⅲ
3, rated power: In the normal atmospheric pressure 90-106.6KPa
and the environment temperature of the chip resistance parameters of -55
℃ ~ +70 ℃ under the conditions of long-term resistance allows the
dissipation of the larger power.
Wirewound resistors rated power series (W): 1 / 20,1 / 8,1 / 4,1 / 2,1,2,4,8,10,16,25,40,50,75,100, 150,250,500
Non-linear wound resistors rated power series (W): 1 / 20,1 / 8,1 / 4,1 / 2,1,2,5,10,25,50,100
4, the rated voltage: resistance and rated power conversion chip resistance parameters out of the voltage.
5, high working voltage: allow patch resistance, patch resistance parameters of the larger continuous voltage. When working at low pressure, high operating voltage is lower.
6,
the temperature coefficient: the temperature changes of 1 ℃ caused by
changes in the relative resistance, the smaller the temperature
coefficient, the better the stability of resistance, resistance
increases with temperature for the positive temperature coefficient, on
the contrary is negative temperature coefficient.
7, the aging coefficient: resistors rated power at long-term load, the
percentage change in the relative resistance, chip resistance, chip
resistance parameters It is the length of the resistor that the
parameters.
8, the voltage coefficient: Within the specified voltage range, the
voltage change of 1 volt, the relative change in the resistor.
9,
noise: an irregular voltage fluctuations arising in the resistor,
including thermal noise patch resistance, chip resistance parameters and
current noise of two parts, thermal noise is due to the internal
irregular conductor of electrons free movement, the conductor Any two irregular voltage changes.
