Ceramic Resistors Advantages

Since they fail open circuit a small low value resistor can be used instead of a more expensive fuse.

Ceramic resistors advantages.

While an excellent electrical insulator ceramic is also an excellent heat conductor. 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. 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. They can have very tight resistance tolerances say 0 005 is commonly achieved.

Wirewound resistors have longer life compared to other types. Sometimes referred to as ceramic power resistors due to their resistance levels ceramic resistors have definite advantages over other resistors. Ceramic s use however is not limited to the internal components of resistors. These precision wire wound resistors are available up to 5 w with and 1 tolerances and are useful upto 5 to 10 mhz.

This property of ceramic allows the cores of these resistors to endure low to moderate power electrical current throughput without overheating and becoming damaged. Precision wire wound resistors are wound on ceramic tubes and sometimes epoxy moulded tubes are used. 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. Advantages very cheap and easy to replace.

Wirewound resistors are one of the first practical resistors used since from the beginning.
