Resistors

Thick film rectangular

MCR01 (1005 size : 1 / 16W)

zFeatures

1) Extremely small light Area ratio is 60% smaller than that of chip 1608, while weight ratio has been cut 75%.

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) Flat surface further facilitates mounting Mounting can also be automated.

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.

zBefore using components in circuits where they will be exposed to transient s such as pulse loads (short–duration, high– level loads), be cert ain 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 volt age.
