CONSTRUCTION
The resistor is 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 approximately required resistance value. The whole element is covered by a
protective overcoat. The top of overcoat is marked with the resistance value. Finally, the two external
terminations (Ni/matte tin) are added, as shown in Fig.5.

POWER RATING
Each type rated power at 70 °C:
SR0402: 1/16W, 1/8W, 1/5W
SR0603: 1/10W, 1/5W, 1/4W

SR1218: 1W, 1.5W
SR2010: 3/4W, 1.25W
SR2512: 1W, 2W
R ATED VOLTAGE
The DC or AC (rms) continuous working voltage
corresponding to the rated power is determined by
the following formula:
V=
Fig. 6 Maximum dissipation (P max ) in percentage of rated power
as a function of the operating ambient temperature (T amb)
(P X R)
Where
V = Continuous rated DC or AC (rms) working voltage (V)
P = Rated power (W)
R = Resistance value (Ω)
