MMU 0102, MMA 0204 and MMB 0207 professional thin film

MELF resistors are the perfect choice for most fields of

modern professional electronics where reliability and stability

is of major concern. The typical applications in the fields of

automotive, telecommunication and medical equipment

reflect the outstanding level of proven reliability.

FEATURES

 Approved to EN 140401-803

 AEC-Q200 qualified

 Advanced thin film technology

 Excellent overall stability: Exceeds class 0.25

 Matte Sn termination on Ni barrier layer

 Compliant to RoHS Directive 2011/65/EU

APPLICATIONS

 Automotive

 Telecommunication

 Industrial

 Medical equipment

Notes

• 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.

printed-circuit board (thermal resistance). 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.
