Because of its insulation and thermal properties, ceramic is used to externally insulate and provide even greater thermal endurance to some types of resistors. The most common of these types are resistors made of resistive wire spun around a ceramic core and then encased in a block or cylinder of ceramic material.
What is inside a ceramic resistor?
Ceramic resistors are manufactured from a sintered body of ceramic material, with conductive particles distributed throughout the matrix, to produce a resistor that is 100% active and non-inductive. Ceramic resistors are chemically inert.

How do cement resistors work?
Cement resistors are made to handle a large amount of power flowing through it with it being undamaged by heat or flames. If you are designing a circuit where a lot of current is being passed through a resistor and with it needing to be resistant to high heat and flame, cement resistors is a good design choice.
How are cement resistors made?
SQ cement Resistor are made by winding resistance wires around non-alkaline ceramic core, which is added with a layer of heat and humidity resistant and non-corrosive protective material. The wire wound resistor is then placed in a square ceramic package sealed with special nonflammable heat-resistant cement.
How is a resistor constructed?
Resistors can be constructed out of a variety of materials. Most common, modern resistors are made out of either a carbon, metal, or metal-oxide film. In these resistors, a thin film of conductive (though still resistive) material is wrapped in a helix around and covered by an insulating material.
