ELECTRICAL CHARACTERISTICS * Unless otherwise specified, all values are tested at the following condition: Temperature: 21℃ to 25℃; Relative humidity: 45% to 70%; The parts must be well soldering with good soldering pads. * Rated Continuous Working Voltage (RCWV)= * Resistance value out of range is available on request. * Terminal caps of the resistors are all with three electroplating: the inner is copper Power Rating  Resistance Value plating + nickel plating to minimize the tin whisker phenomenon and final plating is tin to improve the solderability. The thickness of 3 layers of 0204 size are Cu:>0.8μm + Ni:3μm. * The post high temperature treatment after final tin plating is strictly controlled by our production procedure to minimize the tin whisker phenomenon * The resistances of all jumpers are lower than 15mΩ www.thunder-resistor.com sales@thunder-resistor.com 4 of 9 6. Derating curves The power dissipation on the resistor generates a temperature rise against the local ambient, depending on the heat flow support of the printed-circuit board (thermal resistance). The rated dissipation applies only if the permitted film temperature is not exceeded. These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime. For MELF resistors working at an ambiance temperature of 70℃ or above, the power rating shall be derated in accordance with the above curves. 7.
