CONSTRUCTION
A metal film layer is deposited on a high
grade ceramic body (aluminium oxide).
This resistive layer is trimmed to its
nominal value and on both ends a contact
is made which will guarantee optimum
solderability. This is achieved by applying
several layers and for ease of soldering the
outer layer consists of Ni/matte tin. The
resistive layer is covered with a protective
coating.

FUNCTIONAL DESCRIPTION
OPERATING TEMPERATURE RANGE
Range: –55 °C to +155 °C
POWER RATING
Each type rated power at 70 °C:
AT0402=1/16 W
AT0603=1/10 W
AT0805=1/8 W
AT1206=1/4 W
R
ATED VOLTAGE
The DC or AT (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V=
(P
xR)
Fig. 10
Maximum dissipation (P
max
) in percentage of rated power
as a function of the operating ambient temperature (T
amb
)
Or max. working voltage whichever is less
Where
V=Continuous rated DC
or AC (rms) working voltage (v)
P=Rated power
R=Resistance value (Ω)
