MCR03
Resistors
Thick film rectangular resistors
MCR03 (0603 size)
Features 1) Power rating of 1 / 10W 2) Highly reliable chip resistor Ruthenium oxide dielectric offers superior resistance to the elements. 3) Electrodes not corroded by soldering Thick film makes the electrodes very strong. 4) Resin protective coating for FX, D resistors Absorbs impact, facilitates mounting. 5) ROHM resistors have approved ISO-9001 certification. Design and specifications are subject to change without notice. Carefully check the specification sheet supplied with the product before using or ordering it.
Ratings
Item Rated power Conditions Power must be derated according to the power derating curve in Figure 1 when ambient temperature exceeds 70C.

AMBIENT TEMPERATURE (C)
Fig.1 Rated 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. E= Nominal resistance Operating temperature PxR E: Rated voltage (V) P: Rated power (W) R: Nominal resistance () Limiting element voltage 50V

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.
