Ceramic resistors advantages.
Wirewound resistors are one of the first practical resistors used since from the beginning.
Ceramic s use however is not limited to the internal components of resistors.
They can have very tight resistance tolerances say 0 005 is commonly achieved.
While an excellent electrical insulator ceramic is also an excellent heat conductor.
Since they fail open circuit a small low value resistor can be used instead of a more expensive fuse.
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.
Wirewound resistors have longer life compared to other types.
The important characteristics of wirewound resistors is its precision.
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.
Sometimes referred to as ceramic power resistors due to their resistance levels ceramic resistors have definite advantages over other resistors.
