APPLICATION INFORMATION
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). The rated dissipation applies only if the permitted film temperature is
not exceeded. Furthermore a high level of ambient temperature or of power dissipation may raise the temperature of the solder
joint, hence special solder alloys or board materials may be required to maintain the reliability of the assembly.
These resistors do not feature a lifetime limitation when operated within the limits of rated dissipation, permissible operating
voltage and permissible film temperature. However, the resistance typically increases due to the resistor’s film temperature over
operating time, generally known as drift. The drift may exceed the stability requirements of an individual application circuit and
thereby limits the functional lifetime.
Notes
• TCR 10 ppm/K and TCR 05 ppm/K is specified over the temperature range from -10 °C to +85 °C.
• UMA 0204: Approval to EN 140401-803, “Version A” is achieved for TCR 10 ppm/K with 0.25 % and 0.1 %.
