Overview

Cement resistors are power resistors that are heat and flame resistant.
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.
Typical power ratings range from 1W to 20W or more.
Tolerances from the stated resistance value are around 5 percent.

Power Rating

Rated power is maximum power which can be continuously loaded at specified ambient temperature

70℃,as Table-1;however when the ambient temperature exceeds 70℃,rated power should be determined

from the derating curve of Fig.1.
