UCR18

www.DataSheet4U.com Low Ohmic Compact Thick Film Chip Resistors UCR18 (3216(1206) size : 1 / 2W) zFeatures 1) Chip resistors ideal for current detection. (11mΩ to 100mΩ) 2) Unique chip and terminal configuration reduces resistance shifting during the mounting process. 3) Superior rated power. 4) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification zRatings Design and specifications are subject to change without notice. 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 0.5W (1 / 2W) 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 Table 1 Resistance range (Ω) Resistance tolerance Special specification Resistance temperature coefficient (ppm/°C) 0.011 to 0.018 (E24) 0.020 to 0.039 (E24) 0.043 to 0.091 (E24) 0.1 F (±1%) J (±5%) L S 0 to 350 0 to 200 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 canno...
