1 / 5 page MCR25 Resistors Rev.A 1/4 Thick film rectangular Low Resistance Series MCR25 (3225 size (1210 size) : 1 / 2W) Features 1) Highly reliable chip resistor Ruthenium oxide resistive material offers superior resistance to the elements. 2) Electrodes not corroded by soldering Suitable for re-flow soldering. 3) ROHM resistors have approved ISO-9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet before using or ordering it. Ratings 0.5W (1 / 2W) E = P × R −55°C to +125°C 2.23V(10 Ω) at 70 °C Item Conditions Specifications Rated power Rated voltage Operating temperature Nominal resistance See Table 1. Limiting element voltage The voltage rating is calculated by the following equation. If the value obtained exceeds the limiting element voltage, the voltage rating is equal to the maximum operating voltage. Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70 °C.

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. |
