CONSTRUCTION
The resistors are constructed on top of a high grade
ceramic body. Internal metal electrodes are added at
each end and connected by a resistive glaze. The
resistive glaze is covered by a lead-free glass.
The composition of the glaze is adjusted to give the
approximate required resistance value and laser trimming
of this resistive glaze achieves the value within tolerance.
The whole element is covered by a protective overcoat.
Size 0603 and bigger is marked with the resistance value
on top. Finally, the two external terminations (Ni / matte
tin) are added. See fig.6

Each type rated power at 70 °C:
AF0402=1/16 W (0.0625W)
AF0603=1/10 W (0.1W)
AF0805=1/8 W (0.125W)
AF1206=1/4 W (0.25W)
R
ATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V =
√
(P X R )
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W )
