■ Attention
This product has high temperature coefficient. When measuring resistance, the resistance value can change due
to Joule Heating. Therefore, the measuring current shall be very small in order to prevent the resistance value from
changing. (For example, when the resistor is used at RCWV, temperature of the resistor rise about 15 °C and the
resistance value rise a few percents.) Resistance value may also change due to the ambient temperature. Resistance
value is measured at 25 °C.
