Cement resistors, also known as wirewound cement resistors, are a type of resistive electronic component that provides resistance to the flow of electric current. These resistors are constructed by winding a resistive wire around a ceramic or cement core, and the assembly is then encapsulated in a cement or ceramic casing. 

Cement resistors usually consist of a ceramic or cement core with resistance wire wrapped around it. The entire assembly is then coated with a layer of cement or ceramic for protection. The cement shell has excellent thermal conductivity and mechanical stability. Cement resistors are known for their ruggedness and ability to handle high power levels. The cement shell acts as an effective heat sink, dissipating the heat generated during operation. This makes them suitable for applications where power consumption is a concern. Typically used in power electronics, industrial machinery, motor control, and other applications requiring high power consumption and stability. They are often found in power supplies, amplifiers, and circuits that handle large currents.

The cement housing provides good thermal stability, allowing these resistors to operate effectively over a wide temperature range. This stability is important to maintain the resistor's performance under varying environmental conditions. Cement resistors are valued for their durability, power handling capabilities, and stability, making them the first choice for a variety of industrial and electronic applications.
