Thin Film MELF Resistors

SMM0207 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.

FEATURES

• MELF resistor with high power rating

• AEC-Q200 qualified

• Advanced metal film technology

• Best in class pulse load capability

• Intrinsic sulfur resistance

• Material categorization:

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
