Resistance temperature characteristic is negative resistance characteristic(where an increase in the temperature results in a decreased resistance) for the range of 650℃~700℃, but it will be positive resistance characteristic(where an increase in the temperature results in a increased resistance). However, the resistance is the measured value at the temperature of 1000℃,which means it will different when you measure it in the general atmosphere. Therefore, Awareness is needed on the resistance value when you design a heater.

D3 type (JIS standard R7501 2nd-class)

*rating is the resist for 1000℃ air, a permissible range are ±10%.
