CONSTRUCTION
OUTLINES
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.

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=
Fig. 10 Maximum dissipation (P max) in percentage of rated power
as a function of the operating ambient temperature (T amb)
(P xR)
Or max. working voltage whichever is less
