Where can we get information of the temperature coefficient (TC) of wirewound resistors?
The temperature coefficient of wirewound resistors depends on the resistive material, used to prepare the device.

A datasheet is available for the standard types:
Temperatute Coefficient Wirewound Resistors (KC, KH, KV, KT, KF Series)

Another datasheet is available for KP series:
Temperatute Coefficient Wirewound Resistors (KP Series)

 

What type of resistors is the best choice for current sensing applications?

We need a power resistor with a very low TC?
Power resistors with a low TC typically are wirewound resistors.
If a low TC is mandatory for your application, you need a all welded construction.

More information you will find in our datasheet: CR Series Data Sheet
