UCR10EVHJSFS

Fixed Thick Film Low Ohmic Chip Resistors For Current Detection UCR10 (2012 size : 1 / 3W) Features 1) Superior rated power. 2) Stable, low resistance guaranteed regardless of the surrounding environment. 3) Thick film resistive elements were used to create this lineup of ultra-low resistance products ranging from 11mΩ to 100Ωm. 4) Chip resistors ideal for current detection. 5) ROHM resistors have approved ISO9001- / ISO/TS 16949- certification. Ratings 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 0.33W (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 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 Before 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. www.rohm.com c ○ 2010 ROHM Co., Ltd.
