Carbon ceramic resistor, Physics

Assignment Help:

MANUFACTURING:

Resistive element is prepared in carbon composition, but the filler used is ceramic powder. The sheet resistance is controlled by changing the quantity of carbon and ceramic. Particle size and sintering temperature also play a critical role in achieving the desired ohm values.

Specifications                                                                                                                                                                                            

Range of values                                                                    10 ohm to 4K7

Temperature coefficient of resistance                                       -1500 ppm/0C

Stability                                                                                20%

Tolerance                                                                              20%

Working temperature                                                              very high

Application: They are used in high power application. They are less costly compared to wire wound resistors.
