The ceramic coating combines a high insulation and physical protection with good heat dissipation.

Ceramic resistor power rating.

The recommended value is 80 for fixed resistors and 75 for variable resistors. The ceramic resistors offer the advantages of carbon composition resistors pure resistance stability reliability and pulse stability in power electronic applications though these too have poor tolerance levels typically 10. The film is deposited on a ceramic sheet. Most manufacturers specify the power rating at 70 c and free airflow conditions.

There are ceramic composition resistors available with a power rating up to 1000 w. Typical power ratings are between 4 and 17 watts. The maximum surface temperature is around 300 c and the tcr varies from 250 till 400 ppm c. The power rating of a resistor is the specification given with a resistor that serves to tell the maximum amount of power that the resistor can withstand.

The resistor itself consists of a metal oxide film deposited onto a ceramic substrate.

Thus if a resistor has a power rating of 1 4 watts 1 4 watts is the maximum amount of power that should be fed into the resistor.

P i v. They have power dissipation ratings much lower than those of grid resistors or water resistors and can usually dissipate no more than a few watts provided they have appropriate cooling. The thickness and length of film determines the resistance. Once you know the voltage and the current you can calculate the power that will be dissipated by the resistor by using the power formula.

At temperatures above 70 c the resistor is derated using the electrical stress ratio. The resistance values are between 10kω and 22kω. One of the most significant market drivers in the resistor industry currently is the need for pulse withstanding resistors. Stress ratio operating power rated power.

Because of their extremely small size surface mount resistors have very low power ratings from 1 10 to 1 4 watt.
