Cement resistors are made of resistance wire wound on an alkali-free ceramic core, plus a layer of heat-resistant, moisture-resistant and non-corrosive protective materials. The wirewound resistors are then placed in square ceramic packages sealed with special non-flammable and heat-resistant cement.
Temperature range: -55°C ~ +155°C
Very small, robust and reliable
Sealed with special cement
Excellent moisture resistance
High temperature stability
Ceramic flame retardant package
The recommended washing method is alcohol
A cement resistor is a heat and flame resistant power resistor.
A cement resistor can handle the large amounts of power flowing through it and is not damaged by heat or flame. If you are designing a circuit with a large amount of current flowing through the resistor and it needs to be resistant to heat and flame, then a cement resistor is a good design choice.
