RSE/Y XXX RRRR 5% YN: not inductive version
R: adjustable version P : intermediate grip T : traction version
RSE 31 150R 5%
RSE is the name of the product
31 is the model that corresponds, for RSE family, to the rated power, in this case 31 W
150R means 150 Ω that is the nominal ohmic value at 20°C
5% is the tolerance on the ohmic value, in this case the value of the resistor is accepted when is within 142.5 Ω ÷ 157.5 Ω
Model / Rated power
Resistance value (nominal at 20°C)
MECHANICAL DATA & DRAWING
SURFACE TEMPERATURE CHARACTERISTICS
Except where stated otherwise, Rated power is given at 20 °C ambient temperature. The maximum power that can be dissipated decreases with the increase of ambient temperature. Derating drops to zero at 350°C ambient temperature from nominal rating at 25%.
