Thin Film Mini-MELF Resistors

SMM0204 thin film MELF resistors are the perfect choice for

most fields of modern electronics where reliability and

stability are of major concern. The typical applications in the

fields of automotive, industrial and medical equipment

reflect the outstanding level of proven reliability.

FEATURES

• Advanced metal film technology

• AEC-Q200 qualified

• Approval acc. EN 140401-803 available on

request

• Excellent stability in different environmental

conditions

• Best in class pulse load capability

• Intrinsic sulfur resistance

• Material categorization: for definitions of compliance

please see www.vishay.com/doc?99912

APPLICATIONS

• Automotive

• Telecommunication

• Industrial

• Medical equipment

Notes

• The IECQ-CECC approved product versions SMM0204 EN803 E0 and OMM0204 EN803 E0 respectively feature a quality factor 

= 3 for

the purpose of system MTBF calculations, compared with 

= 10 for the standard versions

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.
