Temperature Correction Function (TC)
The temperature coefficient changes according to the temperature and
conductivity.
If the temperature coefficient at 20°C is a
20
and the temperature coefficient
for conductivity C at t °C is a
Ct
, a
Ct
is determined as follows near the ambient
temperature.
For example, the temperature coefficient of international standard annealed
copper is 3930 ppm/°C at 20°C. For tinned annealed copper wire (with a
diameter from 0.10 to less than 0.26 mm), the temperature coefficient a
20
at
20°C is calculated as follows:
