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 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. The designer may estimate the performance of the particular resistor application or set certain load and temperature limits in order to maintain a desired stability.

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 TEMPERATURE COEFFICIENT AND RESISTANCE RANGE (1) TYPE / SIZE TCR TOLERANCE MBA/SMA 0204 ± 25 ppm/K ± 15 ppm/K ± 0.25 % ± 0.1 % ± 0.25 % ± 0.1 % MBB/SMA 0207 ± 25 ppm/K ± 15 ppm/K ± 0.25 % ± 0.1 % ± 0.25 % ± 0.1 % MBE/SMA 0414 ± 25 ppm/K ± 15 ppm/K ± 0.25 % ± 0.1 % ± 0.25 % ± 0.1 % RESISTANCE (2) 22 Ω to 332 kΩ 43 Ω to 332 kΩ 22 Ω to 221 kΩ 43 Ω to 221 kΩ 10 Ω to 1 MΩ 10 Ω to 1 MΩ 10 Ω to 1 MΩ 10 Ω to 1 MΩ 22 Ω to 1.5 MΩ 43 Ω to 1 MΩ 22 Ω to 1 MΩ 43 Ω to 1 MΩ Notes • Radial version (RB, UB) cannot be qualified according to CECC so these can only be ordered with variant N or S (1) Approval is according to EN 140101-806, version A, or the app.
