4. Derating curve and temperature rising curve
The power dissipation on the resistor generates a temperature rise against the local
ambient, depending on the heat flow support of the printed-circuit board (thermal
resistance). These resistors do not feature a limited lifetime when operated within the
permissible limits. However, resistance value drift increasing over operating time may
result in exceeding a limit acceptable to the specific application, thereby establishing
a functional lifetime.
For high precision resistors working at an ambiance temperature of 25℃ or above,
the power rating shall be derated in accordance with the derating curve.
