Carefully check the specification sheet before using or ordering it. Item Rated power Conditions Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70°C. 100 80 POWER LOAD (%) Specifications 0.33W (1 / 3W) at 70°C 60 40 20 0 −55 0 70 100 155 AMBIENT TEMPERATURE (°C) Fig.1 Rated voltage The voltage rating is calculated by the following equation. E: Rated voltage (V) E= P×R P: Rated power (W) R: Nominal resistance (Ω) Nominal resistance Operating temperature See Table 1. −55°C to + 155°C Rev.A 1/4 www.DataSheet4U.com UCR10 Resistors Table 1 Resistance range (Ω) Resistance tolerance Special specification Resistance temperature coefficient (ppm/°C) 0.011 to 0.018 (E24) 0.020 to 0.047 (E24) 0.051 to 0.091 (E24) 0.1 J (±5%) S F (±1%) J (±5%) L 250±100 0 to 250 0 to 150 0 to 150 zBefore using components in circuits where they will be exposed to transients such as pulse loads (short–duration, high– level loads), be certain to evaluate the component in the mounted state. In addition, the reliability and performance of this component cannot be guaranteed if it is used with a steady state voltage that is greater than its rated voltage. zCharacteristics Item Guaranteed value Resistor type Test conditions (JIS C 5201-1) JIS C 5201-1 4.5 Measuring method : Measure under termination Resistance F : ±1% J : ±5% Under termination Terminal Variation of resistance with temperature Overload See Table.1 JIS C 5201-1 4.8 Measurement : −55 / +25 / +125°C JIS C 5201-1 4.13 Rated voltage (current) × 2.5, 2s.
