Note

• The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to

different film temperatures and different achievable load-life stability (drift) of the resistance value. A suitable low thermal resistance of the

circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please

consider the application note “Thermal Management in Surface-Mounted Resistor Applications” (www.vishay.com/doc?28844) for

information on the general nature of thermal resistance

Note

(1) For the approved IECQ-CECC resistance range, please refer to www.vishay.com/doc?28945
