Professional High Temperature MELF Resistors

MMA 0204 professional high temperature MELF resistors

are the perfect choice for most fields of modern professional

electronics where high operating temperatures, power

rating, reliability and stability is of major concern. These

improved properties are enabled by a modified resistive film

material. The typical applications in the fields of automotive

and industrial equipment reflect the outstanding level of

proven reliability.

FEATURES

• 175 °C specified operating temperature

• AEC-Q200 qualified

• Advanced thin film technology

• Excellent stability, < 0.1 %

• Matte Sn termination on Ni barrier layer

• Material categorization:

Note

APPLICATION INFORMATION

The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow

support of the printed-circuit board (thermal resistance). 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. At the maximum permissible film temperature of 175 °C the useful lifetime is specified for 1000 h. 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.
