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

Note
• The presented operation modes do not refer to different types of resistors, but actually show examples of different loads, that lead to
different film temperatures and different achievable load-life stability (drift) of the resistance value. A suitable low thermal resistance of the
circuit board assembly must be safeguarded in order to maintain the film temperature of the resistors within the specified limits. Please
consider the application note “Thermal Management in Surface-Mounted Resistor Applications” (www.vishay.com/doc?28844) for
information on the general nature of thermal resistance.

MC ATAU - Precision

DESCRIPTION
The MC ATAU series is derived from the precision MC AT
series, datasheet number 28785, which is qualified
according AEC-Q200 and approved to EN140401-801. The
MC ATAU series is manufactured identically except the
termination. Production is strictly controlled and follows an
extensive set of instructions established for reproducibility.
A homogeneous film of special metal alloy is deposited on a
high grade ceramic substrate (Al
2
O
3
) and conditioned to
achieve the desired temperature coefficient. Specially
designed inner contacts are deposited on both sides. A
special laser is used to achieve the target value by smoothly
cutting a meander groove in the resistive layer without
damaging the ceramics. The resistor elements are covered
by a unique protective coating designed for electrical,
mechanical and climatic protection. The terminations
receive a final layer appropriate for conductive gluing.
The result of the determined production is verified by an
extensive testing procedure and optical inspection
performed on 100 % of the individual chip resistors. This
includes full screening for the elimination of products with
potential risk of early field failures. Only accepted products
are laid directly into the paper tape in accordance with
IEC 60286-3 Type 1a
