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

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.
