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.

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
