Ceramic Resistors Advantages

Sometimes referred to as ceramic power resistors due to their resistance levels ceramic resistors have definite advantages over other resistors.

Ceramic resistors advantages. Ceramic s use however is not limited to the internal components of resistors. While an excellent electrical insulator ceramic is also an excellent heat conductor. Precision wire wound resistors are wound on ceramic tubes and sometimes epoxy moulded tubes are used. These precision wire wound resistors are available up to 5 w with and 1 tolerances and are useful upto 5 to 10 mhz.

Advantages very cheap and easy to replace. This property of ceramic allows the cores of these resistors to endure low to moderate power electrical current throughput without overheating and becoming damaged. Here are some advantages of a ceramic kilns it durable fire resistant moisture resistant resistant to abration slip resistance frost resistant stain resistant chemical resistant and color. Since they fail open circuit a small low value resistor can be used instead of a more expensive fuse.

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 winding is so done so as to minimize inductive and capacitive effects at high frequencies beyond 200 khz. Wirewound resistors are one of the first practical resistors used since from the beginning. Wirewound resistors have longer life compared to other types.

For instance the ceramic composition resistor has found wide use as a thermal sensing control element and as a current limiting device due to its relatively low electrical resistance in one temperature range and very sharply increased resistance when heated to an anomaly temperature.
