Ceramic Resistors Advantages

They can have very tight resistance tolerances say 0 005 is commonly achieved.

Ceramic resistors advantages.

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. 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. While an excellent electrical insulator ceramic is also an excellent heat conductor.

The winding is so done so as to minimize inductive and capacitive effects at high frequencies beyond 200 khz. This property of ceramic allows the cores of these resistors to endure low to moderate power electrical current throughput without overheating and becoming damaged. Since they fail open circuit a small low value resistor can be used instead of a more expensive fuse. Disadvantage waste power by turning it to.

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. Wirewound resistors are one of the first practical resistors used since from the beginning. Precision wire wound resistors are wound on ceramic tubes and sometimes epoxy moulded tubes are used. Advantages very cheap and easy to replace.

Wirewound resistors have longer life compared to other types.
