Thin Film MELF Resistors
SMM 0207 thin film MELF resistors are the perfect choice
for most fields of modern professional electronics where
reliability and stability is of major concern at higher power
rating and higher operating voltage. The typical applications
in the fields of automotive, industrial and medical equipment
reflect the outstanding level of proven reliability.

Please refer to APPLICATION INFORMATION below.
APPLICATION INFORMATION
When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal
resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted
film temperature is not exceeded.
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
