Ceramic Resistor Uses

Uses of carbon resistors.

Ceramic resistor uses. These two powders combine in specific ratios to determine the final value of the resistor. A resistor is a passive two terminal electrical component that implements electrical resistance as a circuit element. Ceramic resistors are made of a combination of finely powdered carbon and ceramic material. A ceramic substrate that has a thin bulk metal foil cemented to it makes up the resistive element.

Developed in the 1960s the foil resistor is still one of the most accurate and stable types of resistor that you ll find and are used for applications with high precision requirements. This is my favorite image to show people. In electronic circuits resistors are used to reduce current flow adjust signal levels to divide voltages bias active elements and terminate transmission lines among other uses high power resistors that can dissipate many watts of electrical power as heat may be used as. Depending on the resistance required pitch diameter and length of the carbon spiral vary.

Ceramic and metal oxide if you need a high power non inductive resistor you can use cermet ceramic metal mix or metal oxide resistors. Adjustable resistors there are many different types of adjustable resistors. This makes use of two resistors to divide a voltage by the ratio of their resistances. The construction of a true ceramic resistor often called a carbon composite resistor is different from most other types even though it also uses ceramics.

As seen above resistors can be used to limit the current that flows into a device. A spiral is etched on the deposited carbon which turns it into a wire wound on a ceramic core.
