ROHM MCR10EZHFL Technical data

Low Ohmic Thick Film Chip Resistors

MCR10 (2012 size (0805 size) : 1 / 4W)

Features

1) Power rating of 1 / 4W

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) ROHM resistors have approved ISO9001- / ISO/TS16949- certification.

Ratings
Design and specifications are subject to change without notice.
Carefully check the specification sheet before using or ordering it.

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.
